1. (i) Lineodes ochrea, sp. nov. (Pi. X. fig. i). 

Antennae pale yellowish cinereous. Palpi ochreous, sprinkled with greyish fuscous 
externally. Head and Thorax greyish fuscous, mixed with ochreous and pale cinereous 
scales. Forewings pale brownish ochreous, sprinkled with greyish fuscous scales on a 
short basal patch, produced along the dorsum, where the dark sprinkling becomes thicker 
and is dilated outward and upward nearly to the middle, forming, with a thinner 
sprinkling on the costa before the middle, an ill-defined broad band interrupted by a 
narrow pale cinereous space along the cell ; this is extended outward, gradually widened 
towards the apex, which it does not reach, and is interrupted by an irregular broad 
greyish fuscous band, obliquely placed, crossing the end of the cell, but not reaching to 
the costa or dorsum ; its upper and lower margins are produced respectively in narrow 
greyish fuscous lines which meet and enclose the outer end of the pale cinereous space 
which obviously represents the upper fold of the wing; above it are three or four 

* I retained the genus Lineodes, of which I possessed a fairly representative collection, owing to its 
having been originally included in the Pterophorina ; for this reason Mr Meyrick did not deal with Lineodes in 
treating of the Pyraustidae to which family it belongs. Wlsni.

greyish fuscous costal spots ; a greyish fuscous terminal band precedes the pale 
cinereous cilia through which runs along their middle a somewhat broken greyish fuscous 
line. Exp. al. 22 — 26 mm. Hindwings and cilia pale cinereous, with some slightly 
darker mottlings beyond the cell and along the dorsum. Abdomen brownish ochreous, 
much sprinkled with greyish fuscous. Legs pale cinereous, the posterior ends of the 
tibiae sprinkled with greyish fuscous.

This species resembles Lineodes interrupta, Z., especially in the central and outer 
shades being separated at the costa, but it differs in its ochreous colouring and in the 
pattern of the outer markings. 

2. (2) Lineodes siibextincta, sp. nov. (PI. X. fig. 2). 

Antennae cinereous. Palpi projecting more than the length of the head beyond it ; 
greyish fuscous. Head greyish fuscous, with a small whitish spot on either side behind 
the base of the antennae. Thorax greyish fuscous, mixed with cinereous and fawn- 
brown scales ; tegulae with long hair-like scales at their extremities. Forewings 
cinereous, thickly dusted with greyish fuscous, especially along the dorsal half, with 
a slight admixture of fawn-brown on the costal half before the middle and in a pale 
subterminal band ; the only markings that are traceable are a greyish fuscous shade 
before the middle, crossing the upper fold obliquely backward from the costa and 
reaching the dorsum at about one-third of the wing-length (in some specimens this is 
almost entirely lost in the greyish fuscous suffusion) ; a broad irregular somewhat 
triangular patch embracing the outer extremity of the cell extends to the costa a little 
before the apex, but its lower angle does not reach the dorsum, the basal portion of this 
triangle is somewhat darker through the more thickly packed greyish fuscous scales 
than its outer portion, except a narrow marginal line running parallel with the termen ; 
four dark costal spots precede the apex and a narrow reduplicated greyish fuscous band 
follows the termen from apex to tornus embracing the basal half of the pale cinereous 
cilia, which are also tipped with greyish fuscous, except on the lower third of the 
margin. Exp. al. 21 — 25 mm. Hindwings pale cinereous, with a broad mottled band 
following the outer margin ; cilia pale cinereous. Abdomen greyish fuscous, sprinkled 
with cinereous, with two whitish lateral spots at the extreme base. Hind Legs pale 
cinereous, the tibiae slightly clouded.

Type Merimnetria fiaviterminella Wlsm. 

Antennae (i), widening beyond the base, the stem wide, slightly flattened; serrate 
towards the apex. Maxillary Palpi absent. Labial Palpi recurved to above the vertex; 
smooth ; terminal joint not longer than the median. Haustellum present. Ocelli 
absent. Head and Thorax smooth. Forewings five times as long as broad, the 
margins parallel until tapering off to the lanceolate apex : neuration, 1 1 veins (7 and 8 
coincident to costa) ; 2 and 3 separate. Hindwings as broad as the forewings ; termen 
sinuate below the apex ; cilia longer than the width of the wing : neuration, 8 veins ; 
3 and 4 connate, 6 and 7 remote, but somewhat approximating tov/ards base. Abdomen 
flattened. Legs, hind tibiae somewhat hairy above. 

This genus should be placed in the neighbourhood of Strobisia Clms. and Dre- 
panoterma Wlsm. It may be separated from both by its antennae, which are not 
ciliate as in the latter, and they are longer and stouter than in the former ; both these 
genera differ also in having veins 2 and 3 of the forewings stalked. The uncate 
termen of the forewings in Drepanoterma and the stalking of veins 6 and 7 of the 
hindwings in Strobisia are other points of distinction.

This species was not met with by Mr Perkins. 

-This is the species considered by Mr Butler to be synonymous with the 
Australian convictella Walk. It would be alike unexpected and interesting to find any 
species native to both Australia and the Hawaiian Islands ; but as a matter of fact, 
convictella, Walk., belongs to the genus Eulechria in the Oecophoridae, and differs from 
the above in almost every point of structure ; nor is there even any close superficial 

resemblance." Meyr. '

Oahu, broken and in very poor condition). 

The % has the palpi distinctly paler, being whitish ochreous sprinkled with darker 
scales, the terminal joint is slightly longer than in the $, In the forewings there is less 
cloudy suffusion, the ground-colour being chalky whitish ochreous. The hindwings also 
are much paler than in the $ and may be described as sericeous whitish. The abdomen 
is whitish with transverse bands of tawny reddish brown across the segments, the ovi- 
positor is strongly extruded. 

This species so greatly resembles Thyrocopa gigas Btl., that great care must be 
taken in separating them. In the case of the t no real difficulty arises owing to the 
structure of the antennae, but in the $ it will be found better to rely upon the com- 
parative length of the terminal and median joints of the palpi ; the terminal being much 
shorter in proportion to the median than in Thyrocopa gigas, although there is much 
variation in their relative lengths in this species.

Hab. Kauai : Mts., 3000 — 4000 ft, (i) v. 1894, (5) vi. 1894. Six specimens. 

In some specimens the forewings are more profusely sprinkled and the dark spots 
less clearly defined. Closely allied to argentea Btl, but the markings are arranged 
somewhat differently. In albonubila the three spots along the upper edge of the cell are 
almost in a line, and the anterior is more widely removed from the median than in argentea. 
In argentea the anterior spot is closely approximated to the median and distinctly below 
it. In both species there is a conspicuous dark spot on the costa before one-third, in 
argentea this spot more distinctly precedes that at the end of the fold than in albonubila.

in the form of the hindwings which are broader and shorter ; the cilia are unspotted. 
In the forewings the marginal spots on the underside are less apparent, and on the 
upper side the spot at the end of the cell is not reduplicated — in other respects it would 
be exceedingly difficult to separate them.

On comparing Mr Meyrick's specimens, determined by him as usiiata Btl, on 
which he founded the genus Thyrocopa, I am compelled to regard them as representing 
a species distinct from Dr. Butler's type. It is possible that the error originated through 
the Rev. T. Blackburn having retained in his own collection specimens erroneously 
regarded as representing his No. 69, which he sent to the British Museum. The chief 
points of difference appear to be that the true tisitata Btl has darker, less powdery, and 
more uniformly coloured forewings, and very distinctly darker hindwings, the whole 
insect being more shiny with a slight purplish gloss which is not apparent in Meyrick's 
specimens. The % is larger than the ^, but the average size of specimens is certainly 
smaller than that of the true tisitata Btl, 

The above description is taken from a J in fair condition which was one of the 
original types of ^tisitata Meyr. (nee Btl.) from which the genus Thyrocopa Meyr. 
was described.

Head pale brassy brownish. Thorax dark tawny greyish. Fore wings pale brassy 
brownish, with a tawny suffusion, with the usual two discal spots and one pHcal a little 
beyond the first discal ; the tawny suffusion yields to an indistinct band of the brassy 
ground-colour curved outward beyond the end of the cell and diffused in faint radiating 
lines along the apical and terminal veins ; cilia pale brassy brownish. Exp. al.

costal patches before the apex and some blackish scaling along the base of the stone- 
grey terminal cilia. Exp. al. 28 mm. Hindwings pale cinereous, profusely sprinkled 
throughout with brownish grey scales ; cilia pale cinereous, a shade-line running through 
them near their base. Abdomen greyish fuscous, sprinkled with w^hitish, with narrow

It is probable that a new genus is indicated by this specimen, but in the absence of 
the $ this cannot be determined. The hindwings are narrower than in the typical forms 
of Thyrocopa, and in the forewings veins 7 and 8 are stalked for the greater part of 
their length. A $ from Kona (28685) without a head and in very poor condition 
probably belongs to this species.

Azinis hilarella Wkr. is the % of Theoxenia penicillata Wlsm., the latter names 
must sink as synonyms. No confusion can arise between Azinis hilarella $ and any 
species of Ethnia, the large mat of scales on the underside of the hindwings, which 
are black above except in the flexal region, at once distinguish it. Azinis hilarella %, 
which is with difficulty distinguished from some of the species o{ Ethmia, by appearance 
only, may be at once recognised by the transverse vein connecting the discoidal vein 
to vein 8. The true genus Azinis Wkr. (^^ Theoxenia Wlsm.) has as yet only been 
recorded from Ceylon. 

No other species belonging to the Oecophoridae occurring in Hawaiia and colonella 
being confined to gardens in Honolulu, where it feeds on a cultivated plant, at present 
unrecorded, it is probable that the species has been introduced with the plant on which 
it feeds from one of the groups of islands. Mr Perkins noted it as " common at Honolulu 
— introduced."

Forewings rather shining white, with three transverse pale brownish ochreous bands, 
narrowly margined with dark brown, the first near the base, the second about the middle, 
the third before the apex, the margins of the latter less pronounced ; at the base of the 
brownish ochreous cilia are a few more brown scales crossing the apex ; with a small tuft

Closely allied to quadrifasciata, but differing in the paler markings and in the 
absence of a pronounced subapical band. The presence of the small tuft of scales on 
the underside of the forewings in the Z a-t once distinguishes honorariella from qiiadri- 
fasciata. 

71. (3) Stagmatophora quadrifasctata, sp. nov. (PI. XV. fig. 22). 

Antennae simple, or slightly serrate towards apex, pale ochreous, the basal joint 
flattened, slightly tufted. Palpi slender, recurved, divergent, the terminal joint longer 
than the median, both smooth ; pale ochreous. Head pale ochreous, the face whitish. 
Thorax pale ochreous. Forewings narrow, elongate, tapering to an acute apex ; shining 
whitish, with four transverse bands^ brownish in the middle, darkened with brownish 
fuscous scales along their margins ; these scales are more or less diffused inward across 
the bands ; the first band is near the base, the second before the middle, the third at 
three-fourths, and the last, inverted, from the costa at the apex to the tornus ; with the 
exception of this last the bands are scarcely inverted and of even width throughout ; a 
slender fuscous line curves around the apex in the pale ochreous cilia which are some- 
what grey-shaded at the tornus and on the dorsum. Exp. al. 12 mm. Hindwings 
narrower than the forewings, acutely pointed ; brownish grey, cilia concolorous. Abdo-

a costal patch at one-third, another at two-thirds, and in an ill-defined obHque ante- 
apical band ; the outer costal patch is produced obliquely downwards and merges in the 
dark speckling of the wing which separates it from a more distinct dark spot a little 
above the dorsum, at two-thirds from the base; this is preceded by others less con- 
spicuous on either side of the fold, but with the exception of the apical fourth throucxh 
which a dark diffused band passes, the whole wing is thickly speckled with brownish 
fuscous scales, the scales constituting the markings being generally slighdy raised ; cilia 
speckled in the same way as the wings, conforming to the darker area on the dorsum 
they become brownish grey ; on the underside of the t there is a small tuft of raised 
scales at the end of the cell. Exp. al. 9 mm. Hindwings brownish; cilia brownish 
grey. Abdomen brownish fuscous. Legs brownish grey with paler spurs.

20. Aphthonetus, gen. nov. 
(d(f>66vr)To^ = unenvied.) 

Type, Aphthonetus diffusa Wlsm. 
Antennae, basal joint slightly enlarged, without pecten ; simple, biserrate towards 
apex. Maxillary Palpi short, appressed to the haustellum. Labial Palpi long, slender, 
recurved ; median joint more or less clothed with slender hair-scales ; terminal joint 
acute, of about equal length with the median, Haustellum scaled towards the base. 
Ocelli absent. Head and Thorax smooth ; face receding. Forewings elongate, lanceo- 
late, costa arched and ciliate outward from one-third, apex obtusely pointed, flexus 
moderately pronounced ; surface with scattered groups of more or less raised scales : 
neuration 1 1 veins (4 and 5 probably coincident) ; 6 out of 7 close to apex, 7 and 8 
stalked, 7 to costa; media weak. Hindwings narrower than the forewings, lanceolate, 
flexus pronounced, costa slighdy arched before middle ; cilia longer than the breadth of 
the wing : neuration 8 veins ; 6 and 7 stalked, enclosing apex ; 2, 3, and 4 remote,

one on the cell a little beyond and above it, with which are a few dark ochreous scales ; 
this is followed by two others in the same line with it on the cell, and half-way between 
them, on the extremity of the fold below, is a larger one touching the dorsmn ; there is 
an indication of similar darkish spots along the base of the costal and terminal cilia 
which are greenish grey. Exp. al. 15 — 18 mm. Hindwings pale slaty grey; cilia 
inclining to brownish ochreous. Abdomen with a leaden grey spot above at the base, 
the first three segments beyond it brownish, the posterior segments silvery grey ; anal 
tuft inclining to ochreous. Legs pale ochreous, somewhat shaded with greyish fuscous 
on the tibiae and first tarsal joints ; hind tibiae with pale ochreous hairs above.

4000 ft., IV. 1894. Twenty-three specimens. 

This is a most difficult insect to describe ; its general appearance is a pale yellowish 
green, with indistinct mottled shading, and small ill-defined raised spots, it has however 
no very characteristic markings, although certainly distinct from all other species known 
to me. 

74, (2) Aphthonetus fugitivay sp. nov. (PI. XV. fig. 25). 

Antennae stout, hoary greyish. Palpi pale hoary grey, dusted with fuscous. 
Head and Thorax hoary greyish. Forewings hoary greyish- white, spotted and dusted 
with olivaceous fuscous, some of the spots on the basal half having an admixture of 
ochreous scales with a tendency to be raised above the wing-surface ; it is difficult to say 
that any spots are more distinct than others, but if such could be selected they would be 
two costal spots, one before and one beyond the middle (above and between which the 
cilia, which extend along the whole margin, are very pale ochreous) and another about 
the end of the fold — the whole wing has thus a mottled appearance without defined 
pattern ; cilia hoary greyish, intermixed with brownish fuscous speckling. Exp. al. 
14 mm. Hindwings and cilia shining, leaden greyish, Abdom.en shining, pale greyish 
cinereous, the usual three smooth basal patches being brownish fuscous. Legs uni- 
colorous, shining, pale cinereous.

Hab. Kauai : Kaholuamano, 4000 ft., iv. 1895. Three specimens. 

The two paratypes are in inferior condition, exhibiting no ochreous scales among 
the darker mottling, but these may well be abraded. 

75. (3) Aphthonetus kauaiensis, sp. nov. (PL XV. fig. 26). 

Antennae cinereous. Palpi cinereous, dusted externally with fuscous. Head and 
Thorax cinereous, the latter somewhat dusted with fuscous. Forewings cinereous, 
dusted with fuscous scales, with a chestnut-brown shade at the base above the fold,

chestnut-brown shade, extending thence to the apex but mottled with pale cinereous ; a 

few blachsh scales arise below the fold on the outer edge of the pale fascia, and son.e 

others about the dorsum at the end of the fold ; cilia brownish grey. Exp al lo-

Hab. Kauai : Mts., 3000-4000 ft, (5) v.-vi. 1894 ; Halemanu. 4000 ft, (17) v. 
1895. Twenty-two specimens. 

This species varies much in the contrast between the darker and paler portions of 
the wmg. In some specimens the oblique cinereous fascia dividing the basal from the 
median portion is quite absent, while in others again the tendency of the shades, at least 
beyond where the fascia should be, is longitudinal ; in intermediate forms the central 
portion is obscurely outlined and tends to assume the form of a large costal triangle 
reaching downward to the fold. The head, thorax and cilia are concolorous with tlie 
wing, the latter usually partaking of the pale stippling which characterises its lighter 
portions. 

The forewings are somewhat narrower and more pointed than in the allied species 
corticicolor and mediocris. 

76. (4) Aphthonetus corticicolor, sp. nov. (PI. XV. fig. 27). 
Antennae bronzy brownish. Palpi pale brownish cinereous, shaded with fuscous 

externally. Head and Thorax brownish fuscous. Forewings dull brownish ochreous, 
much suffused and mottled with tawny brown and fuscous, with tufts of raised scales ; 
an outwardly oblique tawny brown basal patch is followed by a pale oblique fascia, 
almost entirely obliterated by fuscous scaling, this is followed by a wider oblique tawny 
brown band before the middle, diffused outwardly on its lower half and confluent with 
the regular brown and fuscous mottling which extends to the apex ; cilia brownish 
cinereous, tawny fuscous on their basal half at the termen. Exp. al. 12 — 13 mm. 
Hindwings dark brownish grey ; cilia brownish cinereous. Abdomen fuscous. Legs 
brownish cinereous, shaded externally with fuscous.

the brown ground-colour being mapped out in one or more bowed-out wavy shades by 
the intervention of pale brownish ochreous costal patches (one before, one at, and one 
beyond the middle) more or less diffused across the wing ; this is especially noticeable 
in the third or outer patch, its semicircular extension preceding the dark brown apical 
region where some pale brownish cinereous mottling occurs, also around the margins 
and through the cilia ; on the dorsum beyond the middle a pale patch is even more 
conspicuous than those on the costa. Exp. al. 13 — 15 mm. Hindwings greyish ; cilia 
brownish grey. Abdomen and legs pale brownish cinereous.

The distinction of this species from corticicolor, Wlsm., and others is sufficiently 
obvious when looking at them side by side, but the points of difference are exceedingly 
difficult to describe, among these the pale dorsal patch may be chiefly relied upon. 



78, (6) Aphthonetus passerella, sp. nov. (PI. XVI. fig. i). 

Antennae greyish fuscous. Palpi whitish cinereous, shaded with greyish fuscous 
externally. Head brownish cinereous. Thorax greyish fuscous, with some ferruginous 
and cinereous scales. Forewings brownish ferruginous, a greyish fuscous transverse band 
near the base, mixed with a few pale cinereous scales, divides the short ferruginous 
basal patch from a central ferruginous shade, both of which are much mixed with fuscous 
beyond the central shade ; the ferruginous ground-colour is much mottled with pale 
cinereous and interspersed with fuscous streaks, a series of four dark fuscous terminal 
spots running through the greyish fuscous terminal cilia ; costal cilia dark fuscous.

mottled with brownish ochreous along the discal area nearly to the apex, the margins 
conspicuously spotted with dark brown scale-patches which are diffused through the 
basal half of the pale cinereous cilia ; these patches, commencing at about one-third from 
the base, gradually diminish in size outwardly, the first dorsal being opposite to the first 
costal, but the second dorsal opposite to the third dorsal, the costal series consisting of 
about 7, the dorsal series of 4, not including one at the apex ; there are some patches of 
raised scales towards the base, some in the brownish ochreous mottling, some in the 
upper edge of the first brown dorsal patch. Exp. al. 12 — 14 mm. Hindwings grey;

The single specimen is badly set, and the neuration difficult to determine with 
certainty ; it appears to agree with that of rutilellum, but the median joint of the palpi 
is not clothed. The reception of the J will probably justify the description of a new 
genus for this species. 

22. Neelysia, gen. nov. 
{yio% = new ; ^HXvcria = Elysian.) 
Type Neelysia lignicolor Wlsm. 

Antennae shorter than the forewings, serrate, basal joint without pecten. Maxillary 
Palpi very short. Labial Palpi long, slender, recurved, divergent ; median joint smooth, 
terminal joint acute, both joints of about equal length. Haustellum scaled towards 
base. Ocelli absent. Head and Thorax smooth ; face receding. Forewings elongate, 
lanceolate, apex scarcely depressed, obtusely pointed, termen oblique, tornus obsolete, 
jflexus rounded ; without tufts of raised scales : neuration 1 1 veins (4 and 5 probably 
coincident) ; 7 and 8 stalked, 7 to costa ; 6 separate ; media weak, Hindwings narrower 
than the forewings, elongate, lanceolate, apex obtusely rounded ; ^ without subcostal 
hair-pencil ; cilia 2 : neuration 8 veins, all separate ; 6 and 7 approximating towards 
base ; 3 approximated to 2 ; 5 approximated to 6. Abdomen moderate. Legs, hind 
tibiae loosely haired. 

The species are generally variable, the ^ in some species with expansible lateral 
thoracic hair-pencil. Neelysia is probably derived from Hyposmocoma, through 
Dysphoria (or an ally), having veins 4 and 5 of the forewings stalked. The loss of a 
vein in Neelysia and Aphthonetus is thus indicated as caused by coincidence of these 
veins. Aphthonetus differs in emitting 6 of the forewings from 7, in having 6 and 7 
of the hindwings stalked, in the clothing of the median joint of the palpi and the scale- 
tufts on the wing-surface.

Antennae fuscous. Palpi yellowish ochreous. Head and face yellowish ochreous. 
Thorax cupreous, with some yellowish scales on the tegulae. Forewings cupreous, with a 
distinct yellowish ochreous spot on the cell at one-third from the base, obliquely placed, its 
lower extremity attenuated outwards to the fold ; a smaller yellowish ochreous spot lies 
at the end of the cell with a few scales of the same colour on the costa above and 
beyond it (in fine specimens a series of minute semi-connected yellowish ochreous dots 
are visible at the base of the cilia around the apex) ; cilia brownish cinereous, shaded

Chrysoclista tigrina Btl., Ann. & Mag. NH. (5. s.) vn. 406-7, No. 50 (I88I)^ 

Antennae brownish grey. Palpi white, with a brownish grey streak along the 
under side of the median joint. Head straw-white, or ochreous. Thorax straw-whitish, 
tegulae brown. Forewings bright ochreous, with a straw-white streak from the middle 
of the base along the lower edge of the cell and along the fold nearly to its outer 
extremity (this white streak is absent in some varieties) ; beneath it is a short dark brown 
basal streak, below the fold, but not touching the dorsum, while above it is a longer 
dark brown streak commencing at the base of the costa and extended along the upper 
edge of the cell nearly to the middle of the wing, where after two sho^rt inverted 
dentate interruptions from the white streak below it, it is continued in the form of a 
blackish elongate dash extending to the end of the cell, with a few blackish scales 
surrounding a third interruption at the end of the cell ; in varieties in which the white 
streak is replaced by the bright ochreous ground-colour, the two interruptions of the 
dark costo-basal streak coalesce and isolate the outer portion, and the blackish scales 
surrounding the third interruption sometimes extend to the costa, forming an outwardly 
oblique quadrangular patch ; the apex of the wing is beautifully marked by a blackish, 
acutely angled streak, clearly defined on its inner edge, and preceded at its upper 
extremity by a narrow oblique whitish costal streak ; this blackish marginal streak sends 
out short tooth-like projections into the costal, apical and terminal cilia, with small 
whitish dots between them at the base of the cilia which are bright ochreous beyond 
them, tornal cilia brownish grey ; in some varieties the bright ochreous ground-colour 
suffuses the white costal streak and encroaches on the black apical streak, breaking it 
up into spots and exceptionally almost entirely obliterating it. Exp. al. 12 — 14 mm. 
Hindwings and cilia brownish grey. Abdomen dark tawny brownish. Legs brownish

This species varies considerably, the margins of the different shades of colour being 
nowhere clearly defined and blending imperceptibly into each other. In some varieties 
the whitish ochreous dorsal shade obliterates the apical markings, becoming more or 
less suffused with ochreous towards the apex. The dark shading in the fold is strong 
in some specimens and almost absent in others, but the discal spots are always distinct. 

107. (4) Neelysia ftiscodentata, sp. nov. (PI. XVII. fig. 2). 

Antennae whitish ochreous, shaded above with fuscous scales. Palpi stone- 
ochreous ; the terminal joint as long as the median, slightly sprinkled with fuscous. 
Head whitish ochreous. Thorax brownish fuscous. Forewings evenly lanceolate, 
whitish ochreous, streaked and shaded with brownish fuscous; the dark shading extends 
along the costa from base to apex, but is very narrow before and about the middle of 
the wing; it overflows the whole of the base, but is more conspicuously condensed on the 
costa, along the fold and on the base of the dorsum ; in the fold it extends nearly to the 
tornus almost obliterating a rather darker spot of the same colour about the middle of 
the fold ; above and a little beyond this is a more or less conspicuous dark discal spot 
connected with another at the end of the cell by more or less continuous dark shading ; 
above the outer end of the cell the brownish fuscous suffusion extends to the costa and 
apex, and narrowly around the termen ; cilia brownish grey, with minute subochreous 
points along their base (these are the only indication of the pale streaks which in many

obliquely terminated in a sharp point below the costa, and abruptly terminated in a 
second darker brownish projection on the end of the cell ; a dark tawny brown line lies 
in the fold on its outer half, followed by some diffuse shading of a paler tint which is 
also visible along the dorsum ; around the apex a dark tawny brown patch covers the 
costal and terminal margins, sharply angulated at its inner edge by the pale ground-

apex, on the median joint widely, on the terminal joint narrowly beneath. Head and 
Thorax white. F'orewings white, with an ochreous tinge on the terminal area, a pale 
greyish fuscous streak extends from the base along the costa, depressed and attenuated

triangular dark fuscous dash occupying the end of the cell, below which is a narrower 
dash of the same colour along the upper edge of the fold; a white streak from the costa, 
very oblique (more so than in Neelysia repandella), forms an angle towards the apex at 
its meeting with the pale median space, the outer edge of which reverts to the tornus ; 
beyond this the apex of the wing is dark fuscous, with three inverted white tooth-like

shade commencing at the base and overflowing the costal margin as far as the end of 
the cell where there is a small arrow-like spot of blackish scales, margined with whitish 
ochreous, which extends backward along the cell, sending out two short oblique whitish 
ochreous points upward and backward into the dark costal shade ; beyond the end of 
the cell is a reduplicated blackish line running half-way to the apex, and beneath it are 
two or three similar lines following the veins, the last of which is longer than the others 
and lies in the fold ; a slender acutely angled whitish ochreous line, leaving the costa at 
the commencement of the costal cilia, runs nearly to the termen, reverting to the tornus 
and forming with the dark double line from the cell the figure of an arrow-head ; before 
and behind this the colour of the wing is decidedly fawm-brown, and in the cilia beyond 
it are six inverted shining whitish cuneiform streaks, three above and three below the 
apex ; cilia brownish grey, tinged with fawn-brown. Exp. al. 14 — 16 mm. Hindwings

fawn-brown lateral streak above each eye. Thorax brownish fuscous, the tegulae edged 
with dark fawn-brown. Forewings dark fawn-brownish, shaded with brownish fuscous, 
a dark fuscous line running along the fold throughout; a dark fuscous shade, commencing 
about the middle of the cell, is broken into three portions by two pale fawn-ochreous 
rings encircling the inner and outer thirds of it and forming two oblique elongate 
suboval spots with a dark space between them ; at the commencement of the costal cilia 
an outwardly oblique whitish ochreous costal streak is attenuated to a point opposite to 
the middle of the termen where it meets, or nearly meets, a similar streak arising a little 
beyond it on the dorsum ; beyond these streaks are four costal and three or four

dark brown ; face paler. Forewings dull brownish ochreous, almost entirely suffused 
with dark fuscous, in some specimens obliterating the always ill-defined markings which 
consist of the usual two elongate blackish discal spots, the first of which is produced 
outwardly along the cell and sometimes divided into two parts ; another elongate spot is 
traceable in the fold below and before the first discal ; around the apex are very faint 
ochreous spots at the base of the dark fuscous cilia, but much less clearly indicated than 
in the two nearly allied species paltodorella Wlsm., and agnetella Wlsm. Exp. al.

In its blurred and sometimes almost entirely obliterated markings and less con- 
spicuous terminal and cilial spots it differs from the other two species mentioned above, 
but is obviously very nearly allied to agnetella which varies somewhat in the same 
direction. I cannot however regard it as belonging to that species.

running from the middle of the base to the lower half of the termen and dilated to a 
little below the fold in which it leaves a brownish fuscous central streak, some fawn- 
brown scales before and behind it ; immediately above the plical streak is an oblique 
brownish fuscous discal spot, encircled narrowly by pale ochreous, whence a dark streak

along the cell reaches to a similar oblique ocelloid spot at the end of the cell; above and 
beyond this is a pale ochreous costal spot whence a dark fawn-brown band runs around 
the apex and termen, sharply angulated opposite to the apex, embracing the base of the 
cilia in which are a series of wedge-shaped pale ochreous spots, pointing inward, to the 
number of four above and four or five below the apex. Exp. al. 11 — 14 mm. Hind-

In some varieties the paler colours are wanting, the wings being entirely suffused 
with dark purplish fuscous, the central and plical spots being very indistinct, but 
obscurely surrounded by slightly paler colour. In other varieties the fawn-brown colour 
assumes a paler shade, obliterating the pale ochreous median streak and more or less 
suffusing the other paler markings, leaving the darker ones distinctly indicated.

This species differs from petalifera Wlsm,, in the absence of the conspicuous white 
basal streak, and in the form of the white discal spots which are produced into minute 
streaklets, as well as in the colour of the palpi which at once distinguish it.

The palpi of this species are smooth throughout, in this respect it differs from 
poeciloceras, which it greatly resembles. The spot at the end of the cell is scarcely 
traceable in some specimens, and the white scaling, which probably represents the real 
ground-colour, is in some specimens almost entirely obliterated.

This would be difficult to separate from some varieties of argyresthiella were it 
not for the smooth palpi which readily distinguish it. It approaches closely to ningorella, 
but the dorsal streak reaches to the base, and the unevenness on its upper edge is much 
less marked, while the spot at the end of the cell is certainly less conspicuous and the 
cilia are decidedly more inclined to yellowish grey in both wings, giving a brighter and 
paler appearance to the hindwings than can be found in the Maui species.

had to be abandoned for intermediate forms rendered it impossible to maintain any

subdivision however distinct the subdivision appeared to be when founded on a single 
species. 

The genus Hyposmocoma is allied to Mompha Hb., Walshia Clms., and Limnaecia 
Stn., but the hindwings are broaden Some species (e.g. radiatella) are very close to 
Limnaecia^ which they much resemble, but the antennae are not ciliate and the head 
is rougher. 

The union of Stagmatopkora HS., i^~ Pyroderces HS., Meyr.) and Limnaecia 
Stn,, Meyr., would justify the inclusion oi Hyposmocoma in such an extended genus, but 
as at present constituted Hyposmocoma differs from each of these genera as they differ 
from each other. 

Without seeing the t of AtrcTuaea lonchoptera, Stgr., I should not be prepared to 
sink Hyposmocoma as a synonym of Atremaea, Stgr., but I am at least extremely 
suspicious that these genera will be proved to be identical 

The % of Atremaea is practically indistinguishable generically from the broader- 
winged forms which are here included in Hyposmocoma, the palpi resembling those of 
certain species in which they are less slender and in which the median and terminal 
joints are of equal length (e.g. epicharis, Wlsm.). 

The generic name was obviously given in reference to the subcostal hair-pencil, 
''presumably a scent-fan " (Btl. Lc,\ Hyposmochoma (;j(a)/xa = a heap) would be neuter, 
and it seems advisable to make the slight correction to Hyposmocoma (Ko^T7 = hair), 
feminine, which was doubtless intended.

4000 ft, V. 1896 (Perkins). Fifty-seven specimens. 

The species is extremely variable in colour and markings, the tendency in colour 
being towards brownish ochreous or fawn-brown ; the obliquely placed spots tending 
to coalescence, the basal patch and the outer edge of the darker colouring tending 
to be produced outward, frequently forming a streak from the middle of the latter 
extending to the apex. In the females especially, which are somewhat narrower 
towards the apex than the males, the lighter brown colouring seems to be more 
frequently developed, but in a series of fifty specimens showing various intermediate 
gradations, and varying not inconsiderably in size, I am unable to find any permanent 
character by which they can be separated into two or more reliable species. 

It would not be difficult to divide them into two series by measurement, the 
-smaller form at first sight appearing on this account to be distinct, but both series 
exhibit the same modification of colouring and are identical in structure and it would not 
be safe to predict that they could be separated even in the larval stages.

Hyposmocoma sp. ? (^ blackbtirnii Btl.). 

Hab. Hawaii: Mt Kilauea, vii. 1895. (27418 Mus. Wlsm.) 

A single specimen, inseparable in appearance from blackburjiii, differs in having 

veins 4 and 5 of the hindwings connate in one wing and short-stalked in the other. 

The specimen is doubtless abnormal, and being unique it might be rash to name it 

blackburniiy since no similar variation in neuration has been found in the long series 

from Kauai, Oahu and Maui. 

156, (20) Hyposmocoma cupreomaculata, sp. nov. (PL XVHI. fig. 24). 

Antennae pale fawn-ochreous, with dark brown annulations. Palpi pale fawn- 
ochreous, much mottled and shaded with dark brown, especially in a ring before the 
pale apex of the median joint and along the under side of the terminal. Head pale 
ochreous, mottled with dark brown ; face unmottled. Thorax pale fawn-ochreous, 
speckled with dark brown. Forewings pale fawn-ochreous, speckled with dark brown, 
with conspicuous dark coppery brown patches ; a small spot, at the base of the costa, 
indicates the upper end of a basal patch dilated outward to the dorsum and clearly 
defined, at its outer edge, above and below the fold ; a second costal patch, a little before 
the middle of the wing, is followed by another at three-fifths, the latter produced and 
attenuated downward nearly to the fold, where it precedes a tornal spot of the same 
colour, tending to be connected with it by scattered scales ; a larger, and more conspicuous, 
outwardly oblique patch arises a little above the dorsum, before the middle, and is 
clearly defined and dilated to the upper edge of the cell ; cilia concolorous, preceded at 
the apex by a few bright coppery brown scales. Exp. al. 15 mm. Hindwings pale,

and mottled with greyish fuscous ; in the distribution of the dark shading a pattern is 
indicated, rather than expressed, consisting of an ill-defined basal patch bulging outward 
on the fold and above it, but receding to the margins ; an oblique costal streak at one- 
fourth, with a nearly opposite dorsal streak below it ; a costal shade a little beyond the 
middle, with an opposite dorsal shade ; a patch or shade beyond the end of the cell, 
continued to the apex and overflowing the costal cilia, but leaving pale spots along the 
base of the cilia, these are reduplicated along the termen, to the number of about 
three in each series, being also traceable on the under side; the costal cilia are 
preceded by a somewhat distinct pale patch, which is matched on the dorsum opposite 
(the whole wing has a mottled appearance, and the indication of the markings depends 
entirely upon the amount of suffusion which may occur in different specimens) ; apical

are a few brownish fuscous scales projecting along the fold, and in a pointed spot at the 
end of the cell (in some varieties the ground-colour is bone-white, the markings tending 
to split up into separate spots with a greater or less degree of suffusion on the wing- 
surface ; the suffusion in some specimens being confined to the region above the fold, 
while in others the costal portion is quite free from it, the shading following the line 
of the fold and reaching to the apex after angulation downward to the tornus) ; two 
narrow elongate costal spots, one at the base, another at one-third, precede a slightly

The broad ochreous streak sufficiently distinguishes this from all other species in 
the group except subfiavidella $. The specimen is unfortunately unique, but the shape 
of the median streak, its abrupt termination above the tornus without diminution of its 
width, and the consequently narrower costal area overspread by the dark ground-colour, 
gives it a very different appearance. One would expect this species to be sexually 
dimorphic as is the case with subfiavidella, and should a series of specimens be obtained 
from Molokai it will probably exhibit an illustration of close parallelism rather than of 
special identity.

the palpi pale ochreous, scarcely shaded at the base externally. Exp. al. 10 mm. 

The ornamentation of the palpi, the greater extension of the dark streak on the 
costa of the forewings, and their paler colouring, with less contrasted cilia and costa on

The markings on the forewings are so slight and so much blended with the general 
ground-colour as to be scarcely traceable in any recognisable pattern, or even distin- 
guishable, except by carefully changing the angle of incidence, when looking at them in

It is within the bounds of possibility that this may be a mere variety of domicolens

183. (47) Hyposrnocoma impunctata, sp. nov. (PI. XIX. fig. ly). 

Antennae pale fawn, with fawn-brown annulations. Palpi pale fawn. Head and 
Thorax pale fawn, the latter shaded along the middle with fawn-brown. P^orewings 
pale fawn, sprinkled with fawn-brown, with a darker shade of the same, tending to 
brownish fuscous, commencing at the base of the costa, where it is diffused outwardly 
and following the cell, whence it extends to the apex, terminating in a dark spot on the 
basal half of the apical cilia; similar spots are indicated above and beneath it on the 
costa and termen ; thus the main feature of the pattern consists of a dark streak running 
through a pale wing, but the sprinkling of dark scales, almost amounting to suffusion, 
terminates somewhat abruptly about the end of the cell, suggesting a costal and dorsal 
pale patch similar to that which occurs in other species, especially in many forms of

58o FAUNA HAWAIIENSIS 

Hab. Maui : Haleakala, 5000 ft, iii. — iv. 1894, v. 1896. Six specimens. 

Extremely similar to ludificata Wlsm., the markings are, however, more slender. 
The absence of the subcostal hair-pencil and of the white spot in the cilia at the apex 
of the forewings enables this species to be distinguished.

In some specimens the ground-colour of the forewings is sooty brown and the 
ochreous markings are only represented by two faintly indicated opposite spots before 
the apex, and a series of indistinct terminal spots. The usual discal and plical spots are 
visible in specimens in which more or less admixture of ochreous scaling occurs among 
the dark ground-colour, but they are not traceable when this is absent. 

207. (71) Hyposmocoma vermictdata, sp. nov. (PI. XX. fig. 23). 

Antennae and Palpi bronzy brown, the latter with a pale ochreous ring at the apex 
of the median joint and another at the tip of the terminal joint. Head and Thorax dark 
bronzy brown. Forewings dark bronzy brown, with a few pale ochreous scales, these 
form a small vermicular streak, in the basal half of the fold, which is preceded and 
followed by dark fuscous spots — these also occur at the end of the fold and on the outer 
half of the cell ; a small pale ochreous spot lies at the commencement of the costal cilia 
and another on the termen opposite, but a little beyond it ; cilia dark fuscous brown, 
with some ochreous scales along their base divided into minute spots. Exp. al.

This species differs from marginenotata in the absence of the subcostal hair-pencil, 
in the presence of a minute pale streak in the basal half of the fold, in the less distinct 
spotting of the termen and in the position of the tornal spot which is a little beyond the 
opposite costal.

Type t (27932) Mus. Wlsm. 

Hab, Kauai : Kaholuamano, 4000 ft., iv. 1895. Three specimens. 

Very similar to ftdvida, but separable by the pale basal joint of the antennae, by 
the more bronzy tint, the somewhat more abrupt apex of the forewings, and the distinctly 
paler face. The spots are not ocellated as in ocellata. It is very close to adolescents, 
but the more yellowish bronzy fuscous of the forewings distinguishes it from the browner 
species which also possesses more strongly developed $ genital appendages and appears 
to be without doubt distinct. 

209. (73) Hyposinocoma higens, sp. nov. (PL XX. fig. 25). 

Antennae rather stout, brownish fuscous. Palpi rust-brownish, the terminal joint 
fuscous externally. Head rust-brownish. Thorax brownish fuscous. Forewings 
brownish fuscous, with the usual three spots, very difficult to distinguish on the dark 
wing-surface; cilia smoky brownish fuscous. Exp. al. 13 mm. Hindwings brownish

Hab. Maui: Haleakala, 5000ft, in. 1894, v. 1896. Two specimens. 

I have found no species which at all agrees with this. The wings are narrow, with 
very straight costa ; the head, distinct in colour from the unicolorous forewings, leading 
one at first to suppose that it might be a suffused variety of some more clearly marked 
species, but I am quite unable to make it fall into any of the series. 

210. (74) Hyposmocoma ocellata, sp. nov. (PI. XX. fig. 26). 

Antennae dark bronzy brown; basal joint streaked beneath with pale ochreous, and

centre rather darker than the tegulae. Forewings shining, bronzy brown, with a 
purpHsh fuscous spot on the middle of the disc, another before it on the fold, and a 
smaller one at the end of the cell (this and the preceding discal spot are nearly 
connected by a streak of the same colour) each spot more or less distinctly outlined 
with very pale ochreous, of which a slender line runs to the lower edge of the streak on 
the outer half of the cell; cilia brownish grey. Exp. al. 15 — 18 mm. Hindwings

In some specimens a certain admixture of pale ochreous occurs above and below 
the outer end of the cell, giving the wing a somewhat streaky appearance. 

This species is nearly allied to ftdvida, but the hindwings are paler, the fore- 
wings more shining and the spots are pale-margined, whereas in the other species they 
show no ocellation.

face pale brassy ochreous. Forewings and cilia bronzy brown, the latter becoming 
brownish grey towards the tornus ; with three dark fuscous spots, one on the middle of 
the fold, one beyond it on the cell, another at the end of the cell. Exp, al. 15 mm.

This species probably belongs to a new genus differing from Hyposmocoma in 
having veins 4 and 5 of the forewings stalked, thus approaching Dysphoria from which, 
however, it differs in the remote origin of veins 4 and 5 of the hindwings. It would be

In the $ the markings are blackish and the white dorsal patch extends broadly 
to the costa, where it is irrorated with blackish, leaving an angulated blackish basal 
patch clearly defined. Closely allied to nigrodentata but differing in the white cilia and 
in the absence of the black margin to the termen and apex.

Antennae greyish fuscous, the basal joint black. Palpi white, sprinkled with black 
externally and around the terminal joint. Head and Thorax chalk-white. Forewings 
chalk-white, with a blackish streak, sprinkled with white scales, running along the costa 
from the base nearly to the middle and sending off two outwardly oblique projections

4000 ft., Larva on '' Lehua" {^Metrosideros polymorpha ?) and other trees, iv. (i) excL v. 
1895. Five specimens. 

In some varieties the wings are much suffused with blackish and fuscous, the white 
ground-colour being only noticeable as a few small spots near the base, two dorsal spots 
and an angulated fascia, formed by narrow streaks from the tornus and costa, beyond 
which the apical portion of the wing is more or less suffused with brown. In these 
varieties the second projection from the blackish costal streak being surrounded by 
white becomes somewhat conspicuous, as also the thorax which is creamy white. 

The larva lives in an elongate conical case, with overlapping lip at the anterior 
end, the narrower posterior end being obtuse and the whole case having much the 
appearance of a piece of birch bark, but somewhat darker on the upper than on the 
under side, the division between the darker and lighter portions being straight and 
clearly defined. For pupation the case is attached by a short, stiff, thick silken stem 
from the middle of its underlip to the midrib of the leaf. The case is suspended 
parallel with the plane of the leaf, two or three fine silk threads attaching its anal 
extremity to the leaf.

6i2 FAUNA HAWAIIENSIS 

The species varies in size and in the amount of shading on the forewings being 
more or less distinctly indicated. One of the specimens from Hawaii (27406) has paler 
hindwings and the dark shade on the palpi is absent, but I cannot venture to separate 
it, having only one specimen in moderate condition. It is to be regretted that no series 
of specimens is available from any of the islands.

minute spot at the end of the cell ; above and below this the costal and dorsal margins 
show patches of fuscous scales, a few of the same being scattered along the termen and 
apex at the base of the pale fawn-ochreous cilia ; at the extreme base of the costa is a 
narrow fuscous shade followed by another a little beyond it. Exp. al. 12 — 13 mm. 
Hindwings shining, pale grey ; cilia with a slight brownish ochreous tinge; t without 
subcostal hair-pencil. Abdomen cinereous. Legs pale cinereous, the tarsi with faint

dark brownish fuscous externally on the median joint almost to its apex ; terminal joint 
slightly sprinkled with fuscous, especially before its apex. Head pale fawn-ochreous. 
Thorax fawn-ochreous. Forewings fawn-ochreous, with a broad dark brownish fuscous 
shade along their upper third extending from the base to the apex, and to a distinct 
dark fuscous spot at the end of the cell preceded by another on the disc; the dark shade 
is slightly diffused beyond the cell, but sends down, before the middle, an angular pro- 
jection to the position of the plical spot which is not otherwise distinguishable ; the pale 
dorsal portion of the wing is obscurely irrorated with fuscous scales, the bases of the 
fawn-ochreous cilia as well as the cilia themselves being sometimes shaded with brownish 
fuscous. Exp. al. 11 — 12 mm. Hindwings and cilia pale leaden grey, with a brownish 
tinge outwardly ; ^ without subcostal hair-pencil. Abdomen fuscous. Legs pale

In syrrhaptes the dark costal shade reaches only to the two discal spots and to the 
costal cilia, w^hile m paradoxa this shade reaches to the apex and throws down an angular 
projection to the plical spot. The palpi also differ slightly, but the two species are very 
closely allied.

ochreous, a blackish fuscous shade running from the base to the costal cilia, its lower 
edge biangulate, the angles reaching the disc but not to the fold ; a sprinkling of fuscous 
scales about the apex, diffused inward towards the end of the cell, with a few also on the 
tornus at the end of the fold ; without visible discal spots ; cilia bright ochreous on the 
termen, tornal cilia brownish grey. Exp. al. 1 1 mm. Hindwings leaden grey ; cilia

In some varieties the white bands are more conspicuous, being less suffused or 
sprinkled. In one variety (281 12) the white is distinctly suffused with rust-brown 
along the dorsum, the basal patch being also strongly tinged with the same colour. 

This species differs from scolopax in the much more conspicuous white costal spot 
and in the clearer definition of the pattern, also in the form of the outer pale fascia, 
which in this species tends to encroach, above the middle, on the dark space preceding it. 
It differs from tetraonella in the possession of a subcostal hair-pencil. 



297. (161) Hyposmocoma tetraonella, sp. nov. (PL XXIV. fig. 2). 

Antennae brownish fuscous, with distinct white annulations, the basal joint brownish

joint and two fuscous annulations on the terminal joint. Head white, or whitish ochreous, 
sometimes with a brown suffusion. Thorax brownish fuscous. Forewings brown, with 
fuscous speckling, and white, or whitish, ill-defined transverse bands ; the first at one-fifth, 
enclosing a basal patch, dilated outward along the dorsum and more or less connected 
with a median band which encloses the first discal spot ; some white scales occur also 
around the outer discal spot ; a white spot on the costa before the apex tends obliquely 
outward, some whitish scales also about the tornus and termen and in the base of the 
mottled cilia ; a plical spot very slightly precedes the first discal, but these are sometimes 
almost lost in the general suffusion of the dark ground-colour. Exp. al. 11 — 12 mm. 
Hindwings dark tawny fuscous (sometimes paler in the $) ; cilia scarcely paler ; ^ with- 
out subcostal hair-pencil. Abdomen dark tawny fuscous. Legs greyish, hind tarsi very

It would be extremely difficult to justify the separation of this species from sub- 
scolopax but for the absence of the subcostal hair-pencil, it is however if anything 
slightly smaller, more mottled and with darker hindwings.

Some specimens are paler than the type and lose the marginal spots. 

The descriptions of the varieties of this species show a wide range of difference in 
intensity and distribution of colour. I had originally regarded them as distinct, but the 
intergradations are numerous and it appears to me to be one of the rare instances in 
which a species ranging over several of the islands fails to establish for itself any 
recognisable local form. The size as well as the colour of the specimens is very variable 
and this difference is to be found in connection with each separate pattern or peculiarity. 
If anyone had before him the varieties described above without the intermediate 
gradations he would undoubtedly regard them as distinct species, but in the absence of 
a knowledge of their life-histories it seems preferable to describe them as varieties 
rather than species.

This species varies considerably in its colouring and in the shape and intensity of 
the spots. In some specimens a small spot, or streaklet, appears a little removed from 
the base beneath the costa; in some the first discal spot is divided into two parts. Some 
varieties are much paler than others, assuming a pale bone-colour, these are more or less 
obscurely streaked with brownish fuscous shading, nowhere concentrated. The generic 
character of the bold fringe of hair-scales arising from the edge of the costa beneath is 
always apparent in the male.

Type Scardia lignivora, Btl. (Meyr. 1883). 
DiPLosARA, Meyr., Ent. Mo. Mag. xx. 35 (1883). 

Antennae rather stout, serrate ; ^ more strongly serrate, each serration wath a 
fascicle of short cilia (^) ; basal joint moderate, without pecten. Maxillary Palpi 
rudimentary, short, drooping. Labial Palpi moderately long, recurved ; median joint 
considerably thickened above and beneath with dense, somewhat rough scales, 
attenuated towards base ; terminal joint as long as median, acute, posterior edge from 
base nearly to apex clothed with long, dense, obliquely projecting scales. Ocelli absent. 
Haustellum strong, scaled. Head with appressed scales. Thorax not crested. Fore- 
wings elongate, narrow, apex obtusely pointed, termen obliquely rounded, dorsum 
somewhat excavate from vein 3 to i ; surface with large tufts of raised scales : neura- 
tion 1 2 veins ; 7 and 8 stalked ; 3 approximated to 4 ; 4 from angle of cell ; 5 closely 
approximated to 4, remote from 6 ; 11 from middle of radius ; 10 approximated to 9 ; 
media almost obsolete. Hindwings as broad as forewings, elongate-ovate, cilia rather 
long (i) ; i with costal fold containing an expansible subcostal hair-pencil : neuration 8 
veins ; 6 remote from 5, gradually approximated to 7 at base ; 8 free, not connected 
with middle of cell by transverse vein ; 3 about equidistant from 2 and 4 ; 4 from angle 
of cell, 4 and 5 normally stalked, but sometimes connate or even separated by a small 
space ; discoidal weak ; media strong from 6 to base. Abdomen not depressed, $ genital 
segments well-developed ; % with ovipositor extruded. Legs, posterior tibiae clothed 
above with long dense hairs. 

Larva in a flattened case rounded at either end somewhat resembling an old- 
fashioned spectacle case ; feeding on rotten wood. 

The above description is largely copied from Meyrick (/. c.) but some additions and 
modifications have been rendered necessary after carefully studying a long series 
presenting considerable variation in the neuration of the hindwings. 

The series of Diplosara lignivora, Btl., consists of 48 (13 ^ + 35 ?) specimens; 
of these 23 (8 ^? + 15 ?) have veins 4 and 5 of the hindwings stalked, in some the 
stalk is short (almost connate), in others it is long or very long ; 7 (r ^ + 6 $) speci- 
mens have these veins connate in one wing and stalked in the other, the length of the 



MICROLEPIDOP TERA 647 

stalk varying ; 8 (2 ^ + 6 ?) specimens have veins 4 and 5 connate in both wings ; 

3 (?) specimens have these veins connate in one wing and very closely approximated in 
the other, while 7 (2 ^ + 5 $) have them very closely approximated in both wings. 
One specimen (28675, ?) from Kauai, belonging to the series with 4 and 5 connate, is 
teratological, with nine veins, 3 and 3^'' being stalked. 

These variations do not appear to be dependent on locality. The greatest variation 
is shown in the series of 27 from Hawaii (i2k;;7<;kJ;4<;4c:). Only 2 speci- 
mens were received from Lanai (i <; i <.<). The 7 specimens from Molokai do 
not vary, all being < Oahu 4 specimens (3 ^ ; i c). Kauai 8 specimens (2 <-<\ 

4 < ; 2 c), in this series no specimen is >^ in both wings. 

Diplosara lignivora is very variable in size and appearance but such variation is 
individual and cannot be correlated with locality or with neuration.

fold and one at least follows it resting on the outer end of the fold ; a fuscous spot at 
the end of the cell is surrounded by whitish cinereous, the subapical shade varies in 
intensity, in some specimens olivaceous brown with brownish fuscous assuming a 
triangular form upon it ; in others almost losing the dark triangular shade which is 
replaced by some sprinkling, a series of semidetached dark brownish fuscous spots 
occurring around the termen and apex; cilia pale cinereous, profusely dusted and shaded 
with olive-brown. Exp. al. 22 — 36 mm. Hindwings rosy greyish ; cilia and subcostal 
hair-pencil pale brownish cinereous. Abdomen pale olive-brown. Legs pale cinereous, 
with brownish fuscous bands across the ends of the tibiae and on the tarsi.

This species differs from maculipennis, Crt., noticeably in the marking out of the 
veins on the costal half of the forewings by white lines, in which it agrees with 
rectivittella, Z., from Bogota, but from this species it differs in the presence of an angular 
excrescence at the upper edge of the white dorsal streak. If rectivitlella can rightly 
be regarded as a species distinct from the cosmopolitan macidipeiinis then albovenosa 
has at least equal claims, but as the ordinary form is undoubtedly associated with it in 
Hawaiia it is quite possible that the distinctions relied upon may prove to be merely 
varietal, since all the points of difference mentioned by Zeller in his description of the 
South American species appear to come within the range of variation exhibited by the 
common form. In a very lengthy series from wide geographical range I have found no 
variety of niaculipennis exhibiting the distinctly marked lines of veining on the costal 
half of the wing which characterise rectivitlella and albovenosa,

In markings and tone of colour this species most resembles graijiinisy it can be 
separated by the second costal spot (beyond the basal patch) being large, somewhat 
triangular and not reduplicated ; in graminis the second costal spot is broken up into two 
spots, the lower, reniform in shape, being the larger. H. herbarum and stibolivacea are 
both from Lanai, in the former the second costal spot points outward while in the latter 
this spot is smaller, blacker and pointed inwards — the tone of green is quite different in 
these two species.

Hindwings with the cubitus pectinate in the male. 

This is a very variable species ; lattfasciata (from Hawaii) is somewhat similar to 
var. seniitogata but is more suffused with dark tawny fuscous. It would be unsafe to 
consider it an extreme form of corticella on the evidence of a single specimen.

Antennae (^) biciliate 5 ; cinereous, faintly banded above near the base ; basal joint 
greyish fuscous above. Palpi whitish ochreous, shaded beneath the median joint Head 
whitish ochreous. Thorax greyish fuscous, mottled with whitish ochreous and pale 
ferruginous. Forewings brownish ochreous, tending to whitish ochreous around the 
margins and on a pale costal spot at one-fourth ; the short oblique basal patch and a 
broad oblique median shade consist of a mixture of ferruginous and greyish fuscous 
scaling, almost obliterating the paler ground-colour, except along the dorsum ; the 
greyish fuscous tint is most noticeable in a series of costal spots, four of which are con- 
nected with the median shade, two others lie before the apex and a series of smaller ones 
around the termen ; connected with the median shade and basal patch are some groups 
of raised scales, sprinkled with dark fuscous (almost black) and tipped with whitish ;

slightly sinuate below the apex ; with a narrow fold along the limbus beneath, making 
the flexus very distinct and prominent : neuration 7 veins ; 3 and 4 coincident ; 5 and 
(3 + 4) connate ; 6 and 7 stalked. Legs, hind tibiae with densely packed closely 
appressed scales above. 

Eccoptocera comes nearest to Holocola. Meyr., but is distinguished by its notched 
antennae ; Heligmocera, Wlsm., differs in the antennae having a sinuation extending over 
several joints, instead of a notch, and veins 3 and 4 of the hindwings are stalked. 
Strepsicrates, Meyr., has a notch in the antennae, but it is at about one-fifth from the base, 
and veins 7 and 8 of the forewings are separate. Baikrotoma, Meyr., has a notch 
immediately above the basal joint of the antennae, but veins 7 and 8 oi the forewings 
are separate. Proteopteryx, Wlsm., differs in not having the antennae notched, in having 
veins 7 and 8 of the forewings separate and 3 and 4 of the hindwings stalked. All these 



674 FAUNA HAWAIIENSIS 

genera have twelve veins in the forewings and possess costal folds in the t, others 
belonging to this group, e.g. Palaeobia, Meyr., are easily separable from the genera 
mentioned by the absence of the costal fold. 

The only allied genus which agrees with Eccoptocera in having only eleven veins in 
the forewings, a costal fold and notched antennae, is Hendecasticha, Meyr., but while 
Eccoptocera has 7 and 8 stalked and 6 obsolete Hendecasticha has 7 and 8 coincident — 
and therefore no stalked apical veins. 

The coincidence of veins 3 and 4 of the hindwings (an unreliable character among 
the species of these genera) appears to be maintained throughout the long series of 
Hawaiian specimens.

Antennae stone-grey, varying to greyish fuscous of a paler or darker shade. Palpi 
varying from cinereous to fuscous. Head stone-grey, cinereous or dark fuscous. Thorax 
greyish fuscous, sometimes stone-grey. Forewings whitish cinereous, speckled with 
tawny fuscous, a dark tawny fuscous median streak runs from the middle of the base to 
the apex, covering the first half of the fold, and thence diverted upward sending a 
projecting angle to the costa before its middle and extending along the upper edge of 
the cell and beyond it in the same line nearly to the apex (this is sometimes broken up, 
either before or beyond the middle, or in both places, leaving, especially in some of the 
darker varieties, a short dorso-basal patch, a larger median patch attaining to the middle 
of the costa, and an antetornal dorsal patch more or less connected with the apical 
shading : in three specimens, of which a pair were taken in cop,, the darker markings 
become almost entirely obliterated, with the exception of the sinuate terminal shade, the 
dividing lines between the costal streaks, a faint antetornal patch, and a still fainter 
median shade) ; on the base of the costa is a strong fold extending nearly to the middle, 
and beyond the middle are eight short whitish costal streaks in four pairs, varying in 
definition and distinctness but always traceable ; a narrow tawny fuscous shade descends 
from the apex along the upper half of the sinuate termen ; cilia whitish cinereous, 
shaded with tawny fuscous at the apex and along their outer half (in the darker forms 
becoming entirely suffused with fuscous, and in the paler ones almost losing the outer 
shade). Exp. aL 16 — 19 mm. Hindwings brassy brown (varying in the intensity of 
their colouring and becoming in some specimens dark tawny brown), cilia scarcely paler. 
Abdomen varying from pale grey to brown and dark brownish fuscous. Legs cinereous

In some specimens the ferruginous and chestnut-brown, obliquely placed, patch 
extends to the base of the wing along the costa and fold, forming a conspicuous dark 
costal triangular patch, the remainder of the wing, with the exception of the ante- 
terminal dark shading, varying from pale ochreous to brownish ochreous. 

The strongly falcate appearance of this species is not structural but is caused by the 
apical markings.

fold, its basal and costal portion mottled with the paler ground-colour ; a large creamy 
white oblique trapezoidal dorsal patch extends over the fold emitting a reduplicated pale 
band, on its inner side, which reverts to the costa bounding the basal patch ; this band 
is margined by a brownish fuscous shade along its outer side which covers the end of 
the cell throwing a branch to the apex, along the upper edge of the ocelloid patch, and 
another along its inner edge to the dorsum ; the costa is marked with alternate broad 
and narrow brownish fuscous streaks, the latter somewhat less oblique than the former,

Type $ (25184) Mus. Wlsm. 

Hab. Hawaii: Kona, 4000 ft, ix. 1892. Unique. 

Closely allied to Cryptophlebia carpophaga, Wlsm. [Ind. Mus. Notes iv. 105 — 6, 
PL IV. i''"'^ (1899) : V. 121, PI. XV. 2, 2''"^ (1903)], but one noticeable difference is that 
the shade which arises from the dorsum is distinctly more oblique and further 
removed from the antetornal spot than in the Indian species ; moreover, in such 
specimens as possess a transverse anteapical shade, this assumes the appearance of a 
somewhat widened band rather than of a narrow curved line. The larva of C carpopkaga 
feeds in the pods of Cassia fistula and occidentalism and also on seeds of Nephelium litcki. 

The genus Cryptophlebia will probably be found to be widely distributed as C, 
citrivora, Wlsm., is injurious to the fruits of Citrus in Natal and Arotrophora ombrodelta, 
Lwr. & P>gt. (which must also be removed to Cryptophlebia) feeds in New South 
Wales on the seeds of Acacia farnesiana, like illepida, Btl, of which Perkins writes *'(? 
any colour, % not variable," but I find the $ very variable and until the larvae have been 
studied the number of species must be doubtful

Thorax cinereous, a broad band across the base of the tegulae in some pale forms. 
Forewings, t olive-grey, with a greenish tinge, blending to olive-brown in a series of 
oblique costal streaks and in a dorsal patch beyond the middle as also in a narrower 
dorsal patch before the middle ; the costal streaks, to the number of about nine, are 
fuscous at their base, the bases of those beyond the middle being triangular and there is 
a strong fuscous shade along the middle of the wing, widening outward from the base 
to the termen ; an indistinctly indicated ocelloid patch, above the tornus, is bounded by 
pale steel-grey and contains three ill-defined black streaklets ; a dark line runs along 
the base of the greyish fuscous cilia : $ whitish, thickly mottled and blotched with rich 
olive-brown and dark umber-brown on the basal two-thirds and about the apex and 
termen, leaving a conspicuous white patch crossing the end of the cell ; the dark umber- 
brown is distributed from the base along the first half of the fold in an elongate patch 
on the outer half of the cell and in a series of costal streaks, of which one at about 
one-fifth from the base and another a little before the middle are produced obliquely

downwards, being thus longer and more conspicuous than the others ; there is an umber- 
brown spot at the apex, mixed with oHve-brown, and a shade of the same mixture along 
the lower half of the termen, thence slightly inverted upward, the intermediate spaces 
between the dark umber markings and along the dorsum are filled up with rich olive- 
brown, in which the whitish ground-colour scarcely appears before the end of the cell 
except to partially isolate a large quadrate olive-brown dorsal patch before the tornus, 
beyond which an ill-defined ocelloid patch is outwardly bounded by shining, silvery 
scales ; the dark costal streaks on the outer half of the wing are distinctly separated by 
white, and some pale olivaceous-brown shading precedes the darker terminal shade on

This species is very closely allied to the European corticana, Hb., and so far as 
one can judge from a small series it is equally variable in colour and more variable in 
size. 

The females are all paler than the dark male above described, but some males are 
decidedly paler (than No. 28075) and show a tendency to greater suffusion and therefore 
obliteration of defined markings, the median streak being absorbed in the sufifused 
shading, the dorsal markings also being scarcely traceable. On the other hand the 
females tend to develop more clearly defined spots and blotches, varying rather in the 
degree of confluence between them than in the amount of general suffusion of the 
darker colouring over the wing surface — in one specimen the dorsal markings are con- 
fluent, forming a dark blotch which spreads across the wing to the costa.

greyer on its basal, more greenish on its outer half; the paler ground-colour, remaining 
below the fold and in a broad ill-defined band arising from the middle of the dorsum 
and reaching nearly to the costa before the apex, is succeeded by another flush of 
olivaceous greenish which overspreads the apical and terminal portion of the wing, the

Antennae greyish fuscous. Palpi and Head whitish cinereous. Thorax cinereous. 
Forewings whitish cinereous, with pale olive-brown markings and some sprinkling of 
brownish grey scales between and about them ; the markings consist of a series of 
about eight costal streaks, tending obliquely outwards, the first three meeting a broad

This species is so similar to Bactra lanceolana, Hb., in the variation of its colouring 
that a detailed description made from a single specimen could only be misleading. 

The ground-colour is for the most part pale fawn (certainly browner than the 
general idea of the meaning conveyed by the word ''stramineous " as used by Butler). 
The speckling along the costa and dorsum as well as on the disc and the slender lines 
indicating the pattern of the neuration (always more noticeable) are of a darker fawn- 
brown, or even fuscous tint, tending in some cases to blackish. The main feature of 
the variation is in the degree of insistence of a dark shade running from the base to the 
apex through the middle of the wing, in some specimens this is strongly marked, and is 

88—2 



688 FAUNA HAWAIIENSIS 

diffused downward nearly to the dorsum, in others it is entirely absent, but the spots at 
the end of the cell and at the basal third of the fold are nearly always recognisable in 
addition to the speckled appearance of the wing-surface, especially along the margins. 
In size the species also varies considerably (Exp. al. 14 — 34 mm.) as is the case with 
its European representative, and were it not for the uniformly greater length of the 
palpi one could scarcely hesitate to regard it as a mere geographical variety of our well- 
known Bactra lanceolana presenting some exaggerated forms approaching in the width 
of the wing the larger variety of this insect which has so frequently been suspected of 
special distinction. (Described from a series of forty-six specimens.)

After examining a very long series of this species I find I can separate it from 
lanceolana, Hb., by one character only, viz., the comparative length of the palpi which in 
the European species are distinctly shorter. In all other respects the numerous varieties 
found in both regions can be absolutely matched. 

In company with others, at least equally competent to form an opinion, I have 
hitherto regarded straminea as inseparable from lanceolana, Hb., but if we admit the 
value of the longer terminal joint of the palpi, which certainly enables us to separate the 
Hawaiian from the European form, the name sti^aminea may be retained to designate 
this geographical and local race. 

When describing Chiloides, Butler called attention to the "separate emission of the 
second and third median branches " of the hindwings, this observation applies equally to 
very numerous specimens of our common Bactra lanceolana although not to all, and in 
the Hawaiian series exactly similar specimens from the same locality taken on the same 
day vary in this particular. 

Meyrick [Tr. N.Z. Inst xvii. 142 (1885)] has drawn especial attention to the 
identity of the New Zealand and Hawaiian species, and in redescribing Chiloides, Btl., 
(subsequently changed to Noteraula, Meyr.) he laid great stress upon the structure of 
the antennae, but a careful examination and comparison shows that in the Hawaiian 
examples they are uniformly shortly biciliate, whereas the New Zealand examples are 
biciliate from i — i^, the joints having also a more dentate appearance (*' antennae in 



MICROLEPIDOPTERA 689 

male serrate, with whorls of moderate cilia," Meyr.). In describing the genus Badra 
from British specimens, Meyrick [HB. Br. Lp. 456 {1895)] uses the words "antennae 
in t moderately ciliated" in reference to lanceolana, Hb., from which the palpi rather 
than the antennae must be relied upon to separate the Hawaiian species. I have not 
felt justified in reversing Mr Meyrick's decision on the strength of so slight a difference 
but its permanence and uniformity throughout the series might not unreasonably be held 
to constitute a character of special value, and as I am unable to regard Noteraula, 
Meyr., as generically distinct from Badra, Stph., and CMloides, Bd., it would be 
appropriate that straminea, Meyr. (nee Btl.) should bear at least the varietal name 
Badra noteraula (n. n.).

to beyond their middle ; the thorax with a fuscous spot posteriorly ; the wings are of a 
paler (more ochreous) colour, the darkly margined spots and the base of the costal fold 
tinged with rust-browm, the square discal spot merged in an outwardly expanding 
brownish shade, directed towards the tornus. Exp. al. 20 mm. Paratype ^ (25064 —

Hab. Maui: Haleakala, 5000 ft., hi. 1894. One specimen. [? Molokai, about 
4000 ft., 9. VI. 1893 ; ? (26103)]. 

The specimen from Molokai is precisely the form that would be expected in the % 
of this species. The colour and markings also coincide, but the hindwings are more 
densely spotted. Exp. al. 22 mm. I am unable to regard it as a separate species 
although the time of year at which it was taken and the locality preclude any absolute 
certainty since it is obvious that if the two specimens belong to one species there must 
be more than one brood in the year and its distribution must be somewhat extended.

694 FAUNA HAWAIIENSIS 

Forewings with the costa evenly arched before the middle, ^ with a narrow costal fold 
at the base, apex somewhat obtuse, termen convex ; shining, dark olive-grey, blotched 
with tawny fuscous ; a tawny fuscous streak on the fold near the base is diffused on 
either side, merging in lines and reticulations of the same colour, forming an 
indistinct basal patch ; beyond this is a similarly indicated pair of oblique fasciae, one 
before, the other about the middle, not reaching to the dorsum— of the first, the only 
conspicuous part is a dark tawny fuscous triangular blotch, its lower extremity crossing 
the fold, on the second a smaller blotch at the end of the cell is noticeable ; a tawny 
fuscous shade along the termen and apex is preceded by another parallel with it, reach- 
ing the tornus ; the whole central portion of the wing is suffused with a tawny fuscous 
gloss partially obscuring the green ground-colour ; along the dorsum is a series of 
narrow dark fuscous spots extending around the termen to the apex at the base of the 
pale tawny cilia. Exp. al. 27 mm, Hindwings tawny grey, with darker greyish

Antennae greenish grey, narrowly banded above with black. Palpi rather rough 
above, projecting about the length of the head beyond it ; pale greenish grey. Head 
and Thorax olive-green, mixed with fuscous. Forewings very roughly clothed, especially 
along the base of the costa, with an almost equal admixture of olive-green, silvery grey, 
greyish fuscous and dark fuscous scaling, presenting an evenly mottled and reticulated 
appearance on which an oblique basal patch, an oblique fasciaform median shade, a dark 
spot at the end of the cell and four post-median costal blotches are faintly indicated by a 
preponderance of the darker colouring, the pale greenish grey cilia being also reticulated 
with two shades of fuscous. P^xp. al. 34 mm. Hindwings whitish cinereous, with pale 
fuscous shades and mottlings ; cilia pale, shaded along their base. Abdomen cinereous.

Type % (28064) Mus. Wlsm. 

Hab. Hawaii: Mt. Kilauea, viii. 1896. Unique. 

This species greatly resembles ftiscoviridis, and might easily be mistaken for 
its %, but the rough scaling at the base of the costa and the more spotted hindwings 
(which m ftiscoviridis are rather blotched and streaked) are differences which could not 
be expected to occur in sexes of one species. This is almost certainly an Archips but 
cannot be referred with certainty to that genus in the absence of the $.

irregular dark brownish fuscous streaks and spots, and two of the same also at the 
extreme base on either side of the fold ; a series of upright dorsal streaklets before the 
middle precede an irregular ill-defined oblique central fascia, narrowed to a quadrate 
spot at the upper edge of the cell, this fascia is wider on its lower half than above, its 
margins irregularly angulated throughout, a dark costal spot beyond the middle 
precedes others less clearly defined ; the terminal portion of the wing is also much 
spotted with fuscous mixed with olivaceous scales which impart a greenish hue to the 
shining white ground-colour on which they are associated throughout with the delicate 
brownish fuscous reticulations ; cilia whitish, with a few brownish scales intermixed.

Forewings, ^ dark brown, with reddish orange and white reticulated patches ; from the 
costa at one-fourth a band of white runs obliquely outward to the middle of the cell, 
whence it reverts to the dorsum at a right angle, this is interrupted on its upper half by 
two lines and one or two spots of rich reddish orange, its lower half being almost 
entirely suffused with the same colour ; between this and the base the rich brown 
ground-colour is blotched with reddish orange and whitish reticulations, with a short 
interrupted white streak along the base of the median vein ; beyond this angulated basal 
patch are two costal spots of reddish orange mixed with white, a post-median costal 
patch, white reticulated with reddish orange and nucleated with brown on the margin, 
and two or three small costal spots towards the apex ; below the outer end of the fold 
are some obscure reddish orange spots, followed by a large reniform patch above the 
tornus, white reticulated with reddish orange, some reddish orange spots along the 
termen are preceded by an elongate white patch reaching to the apex, much reticulated 
with reddish orange ; cilia brown : % golden yellow, reticulated with reddish orange, 
with bands of rich ferruginous ; a ferruginous costal spot near the base is followed by a 
dark fuscous dot below and beyond it ; an outwardly angulated narrow ferruginous band 
indicates the outer edge of a basal patch at one-fourth and contains a few fuscous scale- 
spots ; it is followed by a small triangular ferruginous dorsal spot before the middle 
which is separated by a short space from a broad ferruginous band extending obliquely 
outward to the costa before the apex, sending from the end of the cell a strong branch, 
parallel with the basal patch, reaching the costa before the middle, two ferruginous 
costal spots lying between these branches ; at the end of the cell, in the ferruginous 
band, is a small dark fuscous scale-patch, from the costa, at the extremity of the

also bounded by a pale cinereous line ; the outer half of this blotch is square and 
abruptly terminated on the upper edge of the cell, where it is narrowly separated from 
a slightly inverted ovoid costal spot of the same colour, also narrowly margined with 
pale cinereous ; this spot is preceded by an outwardly oblique dark costal streak and 
followed by four small square dark costal spots, the outer two of which are connected 
with a small tessellated dark patch below them ; at the end of the cell is another square 
tesselated patch, margined before and behind with pale cinereous, up to the outer edge

Antennae brown. Palpi suberect, extending more than the length of the head 
beyond it, the terminal joint half as long as the median ; dark tawny brown. Head 
and Thorax dark brown, the latter with some paler mottling. Forewings dark brown, 
approaching to fuscous along the cell and below the costa ; a conspicuous, shinina, 
whitish, outwardly oblique, cuneiform patch at one-third is broken on the costa by a 
small brown spot ; a smaller white costal spot, similarly broken, occurs beyond the 
middle ; beneath the costa about the base are two brilliant dark green patches, followed 
by a few scales of the same colour which touch the white costal patch ; a series of 
brilliant dark metallic green patches occur along the fold as well as beneath its base, the 
apical and terminal area being also brilliantly spotted with dark green ; cilia tawny 
brownish. Exp. al. 21 — 24 mm. Hindwings and cilia shining, pale yellowish brown. 
Abdomen and Legs pale yellowish brown. 

Type ? (28042) Mus. Wlsm. 

Variation. — Some specimens differ from the type in the absence of the white 
blotches on the forewings and in the further distribution of the metallic green patches 
over the area occupied by them ; with these exceptions the coloration is similar. 

Paratype $ (28629) Mus. Wlsm. 

A small $ probably belonging to this species is somewhat worn ; it possesses 
no white costal patches and is of a generally paler brownish hue, mottled with 
pale brownish cinereous, the position of the patches being indicated in this 
colour ; the green patches are quite invisible, except at a certain angle in a strong light, 
they are somewhat more profusely distributed and more confluent, also, if anything more 
brilliantly iridescent and there is an indication of a small whitish spot at the end of the 
cell. Exp. al. 15 mm. The palpi are very decidedly shorter than in the ? ?, especially 
the terminal joint, and it is possible that a closely allied species may be indicated.

steel-green scales being strewed over and between the blotches in broken transverse 
bands ; the ochreous blotches prevail on the basal third of the costa, on the middle of 
the dorsum and in the terminal and apical regions, a small patch also occurring a little

Antennae dark brownish fuscous, the basal joint tipped with ochreous. Palpi, pro- 
jecting more than the length of the head beyond it, the median joint hirsute above and 
beneath, the terminal joint obtuse, nearly half the length of the median ; brownish 
fuscous mixed with whitish ochreous. Head brown above, hoary fuscous in front. 
Thorax white, shaded anteriorly with fawn-brownish. Forewings with large blotches 
of dark brownish fuscous mixed with shining, dark blue-grey scales, the first forming an 
extended dorso-basal patch, its outer edge angulated inward on the fold, its lower margin 
extending to the middle of the dorsum while its upper edge is separated from the costa 
by a whitish ochreous band in which are three or four dark brownish fuscous costal 
spots ; this band, deflected outward to the dorsum, separates with two slight interruptions 
the basal patch from an even larger triangular costal patch of the same colour, also 
strewed with some shining, blue-grey speckles ; this extends from about one-fourth from 
the base nearly to the apex and contains beyond the middle a shining, whitish ochreous 
spot, interrupted by a dark costal dot ; the lower extremity of the triangle reaches to 
the fold where it is somewhat strewed with olive-brown ; the space between this and 
the termen is shining, olivaceous ochreous, mottled with whitish, containing two curved 
transverse bands of olive-brown spots diffused and blended, the one along the termen, 
the other, within and parallel to it but meeting on the dorsum before the tornus ; apex 
and cilia chequered with greyish fuscous and whitish ochreous, some small almost pure

white scale-spots at their base on the middle of the termen and at the tornus. Exp. al. 
26 mm. Hindwings brownish grey, the cilia on their outer half very pale greyish 
cinereous. Abdomen and Legs brownish grey. 

Type ? (26871) Mus. Wlsm. 

Variation. — In a small ^, almost undoubtedly belonging to this species, the lighter 
markings are unaccompanied by white scaling and are decidedly of a browner hue ; the 
first pale costal blotch is strongly interrupted above the fold by the outward diffusion of 
the basal patch which, after reaching the end of the cell, is attenuated to the tornus. 
Exp. al. 2 I mm. The antennae are slightly serrate, with very short ciliations. The 
thorax is dark brownish fuscous with pale brownish anterior and posterior margins.

This species has much the appearance of an Oxygrapha, but the neuration, although 
utterly abnormal in the left forewing of the type (14 veins; 2 and 11 both outwardly 
furcate, the latter from a narrow supplementary cell ; 3 and 4 connate ; 8 furcate at 
base, one fork connate with 7, the other connected with 9 near its origin) proves it 
distinct from that genus.

Zeller when describing Opogona remarked that although at first sight dimidiatella 
appeared to be an Elachista allied to fuodestella, Dp. [i.e. Asychna, Stn.] its nearest ally 
was Oenophila N-flavwn, Hw. Staudinger (Berl. Ent. Zts. xiv. 325) regarded Opogona 
as intermediate between Bucculatrix, Z. and Phyllobrostis, Stgr. 

Staudinger and Rebel (Cat. Lp. Pal. 11. 220) place Opogona in Lyonetiadae between 
Bucculatrix and Opostega, thus following Staudinger and Wocke (Cat. Lp. Eur. 335), but 
removing Opostega from the N epticulidae to the Lyonetiadae, 



MICROLEPIDOPTERA ^ , . 

Walker placed his genus Cachura at the end of the Lyonetiadae following 
Bucculatrix, with Leucanthiza, Clms., intervening. 

Stainton described Lozostoma as one of the Elachisiidae allied to Cosmopteryx, Hb., 
\Lo20stoma (t Loxostoma) is invalid being homonymous with Loxostovia, Biv. (1838) 
Moll^^, Meyrick (Pr. Lin. Soc. NSW. xxii. 415) followed Stainton in referring 
Lozostoma to the Elachistidae which he defined as having ''Maxillary palpi rudi- 
mentary," but Opogona dimidiatella, Z., zx\^ panchalcella, Stgr., Lozostoma flavofasciata, 
Stn., and sterodyta, Meyr., etc., Cachura ol)jectella, Wkr., Argyresthia (?) aurisi]iiainosa, 
Btl, and various Malaysian and Australian species all agree in having the maxillary 
palpi strongly developed and folded. It therefore follows that Opogona, Z. {^Lozostoma, 
Stn.) is approximately correctly located in the Tineidae in the neighbourhood of 
Opostega, Z., while its nearest ally is perhaps Dendronettra, Wlsm. (Pr. Z. Soc. Lond. 
l8gi, 509—10, PL XLI. 6) which is apparently an older and less specialised form than 
either Opogona or Opostega. 

Opogona aurisquaniosa, Btl., has been bred from sugar-cane and banana in Hawaiia 
and subcervinella. Wkr. (n. %yn.=^plu7nipes, Btl.) is noted as injurious to developed 
sugar-canes and in potatoes and other stored tubers in Mauritius. Unfortunately we have 
no exact record of the habits of either species, but van Deventer [Tijd. Ent. xln'ti. 
83 — 4' PI- X. 1^-^(1904)] figures and describes the larva of Opogona fiiviiceps, F. & R., 
feeding on the Kokos-palm in Java. 

Meyrick [HB. Br. Lp. 728 (1895)] remarks of Opostega '' Larva almost unknown," 
which sums up concisely the present state of our knowledge of this genus. 

Stainton [Ent. Ann. 1868, 133] mentions the breeding of a crippled specimen of 
Opostega auritella, Hb., from flower-stalks of Caltha palustris by Sleich, and Buttner 
[Stett. Ent. Ztg. xli. 468, No. 2966 (1880)] records the breeding of a second cripple by 
Knaack from the same plant. Warren [Ent. Mo. Mag. xxv. 145 (1888)] states that he 
had by chance bred two specimens of salaciella, Tr. (these apparently fed among the 
flowers, or in the flower-stalks, of Rumex acetosella) and suggests that crepus- 
culella, Z., may feed in Mentha palustris, and spatulella, HS., in the flower-stalks 
of Wych-elm.

beyond which is a narrow, oblique, shining, steel-grey fascia narrowly dark-margined on 
either side and slightly angulated a little above the fold ; beyond this the ground-colour 
is pale brownish ochreous, containing two short, shining, steel-grey costal streaks, narrowly 
dark-margined, and a large jet-black terminal patch, reaching from tornus to apex, con- 
taining two upright steel-grey streaks near its opposite extremities, and a single bright 
silvery dot in its middle ; a very narrow ochreous line separates it along the middle 
from the termen above the tornus; cilia shining, leaden grey. Exp. al. 9 — 10mm. 
Hindwings tawny blackish ; cilia tawny greyish. Abdomen greyish fuscous above, 
banded with white beneath. Legs pale greyish fuscous, spurs white.

fuscous externally, the terminal joint fuscous beneath. Head fuscous ; face yellowish 
white. Thorax blackish. Forewings black, with a slight brownish gloss, a white spot 
at the extreme base below the middle and three short, outwardly oblique, white dorsal 
streaks, one near the base reaching to the fold, the second before the middle, crossing 
the fold, the third, shorter, at about the end of the fold ; a little beyond the third dorsal 
is an oblique, narrow, spatulate leaden grey costal streak, which is succeeded by three 
white streaks in the costal cilia before the apex ; at the apex is a black spot, separated 
beyond it by leaden grey and below it by chestnut-brown, from a black curved line 
around the base of the leaden grey cilia which blend with tawny fuscous about the 
tornus. Exp. al. 9 mm. Hindwings blackish; cilia tawny fuscous. Abdomen blackish,

Mts,, 3000 — 4000 ft, (2) VL 1894. — ^Oahu : Waianae Mts., 1400 ft, on the leaves of a 
berry-bearing plant called "Kikania" (11) iv. 1892. — Molokai : sea-level, (1) v. 1893; 
above 3000 ft, (1)5. vt 1893. Seventeen specimens. 

The larva makes a slender tortuous mine, in which the frass is disposed in a con- 
tinuous thread along the middle, in the upper side of leaves of (?) 

This mine commences sometimes at the mid-rib, sometimes at the outer edge of the 
leaf and terminates in an ovate blotch equal to about one-fifth of the width of the leaf 
itself in such specimens as I have before me (27968 — 70). Its habits appear to be 
most similar to those of coffeifoliella, Ntnr., and latifoliella, Mill. & Rgt Mr. Perkins 
who bred this species in Kauai made the following note " bred from blotch, or mine 
and blotch combined, on various plants, v. 1895. Pupa butterfly-like, living in web on 
leaves." He also found it (apparently the imago) ''on the leaves of a berry -bearing 
plant called 'Kikania'" in Oahu. There is obviously some error of observation in 
Mr. Perkins' notes, the larvae of some other Tineid must have been collected inadver- 
tently with those of G. marginestrigata. 



429. (2) Gracilaria epibath^a, sp. nov. (PL XXV. fig, 27). 

Antennae brownish. Palpi white, a small spot on the outer side of the median 
joint at its apex. Head shining, dirty whitish, a few brownish scales posteriorly. 
Thorax olive-brown. F'orewings olive-brown, with three outwardly oblique broad 
pearly white dorsal streaks ; the first near the base, somewhat rounded at its apex ; the 
second at the middle, attenuate ; the third near the tornus, quadrate ; above the latter 
is an outwardly oblique slender white costal streak, followed by two smaller white 
streaks in the costal cilia before the apex ; at the end of the oblique costal streak is a 
small patch of shining, blue scales, narrowly surrounded by pale ochreous ; with a black 
spot at the apex, followed by shining blue at the base of the cilia ; through these runs a 
curved metallic blue line, the space between which and an outer curved brownish line 
being whitish, tornal cilia smoky brownish. Exp. al. 7 mm. Hindwings brownish, 
with slightly paler cilia. Abdomen dark brown. Legs brownish, with whitish tarsal 
spots.

61. Paraphasis, gen. nov. 

(7rapa^a<Tts = consolation.) 

Type Paraphasis perkinsi, Wlsm. 

Antennae three-fourths the length of the forewings ; bipectinate 5 — 6, the 
pectinations remote from each other, biciliate. Head rough. Labial Palpi porrect, 
projecting more than the length of the head beyond it, somewhat roughly clothed, the 
terminal joint short, depressed. Maxillary palpi short. Haustellum well-developed. 
Ocelli (not apparent). Thorax [denuded]. Forewings with the costa slightly arched 
towards the base ; apex slightly depressed, obtuse ; termen oblique, dorsum nearly 
parallel with costa along the middle: neuration 12 veins, all separate; 7 to termen, 
3 and 4 approximating towards base. Hindwings as broad as the forewings, apex 
obtuse, termen evenly rounded: neuration 8 veins; 3 and 4 connate; 5 bent over 
towards origin of 4 ; an internal vein between 5 and 6 ; 6 and 7 separate. Abdomen 
much constricted at base. Legs smooth. 

This genus belongs to the group oi Dissodena, Stgr., Melasina, Bdv., and Compso- 
ctena, Z., with all of which it agrees in having bipectinate antennae, but the persistence 
of palpi and haustellum is interesting. Its antennae most resemble those of Dissoctena, 
but the well-developed palpi at once distinguish it, as also the neuration of the hind- 
wings. The most critical point of difference between this and allied genera is ''3 and 4 
connate" in the hindwings, the usual tendency being towards approximation of 4 and 5. 



440. ( I ) Paraphasis perkinsi, sp. nov. 

Antennae pale cinereous, the pectinations brownish fuscous. Palpi dark ferru- 
ginous. Head and Thorax fawn-brownish. Forewings dark fawn-brownish, mottled 
with dark ferruginous and dark steel-grey, tending to form alternate, outwardly convex, 
transverse lines, not distinctly defined, except a little beyond the end of the cell ; an 
inverted dark ferruginous dorsal blotch obscures the outer end of the fold, and is diffused 
upward across the middle of the cell ; cilia ochreous on their outer half, dark fawn-grey 
on their basal half. Exp. al. 14 mm. Hindwings and cilia dark brownish grey. 
Abdomen greyish fuscous. Legs brownish grey.

black. Under wings of a silvery grey, darker towards the hinder margin. Legs and 
tarsi black-brown, with the joints light Length 4 — 10 inch. The larva in the dried 
state is about 4-ioths of an inch long, largest just behind the head, of a dull red colour, 
with the head dark brown." 

** The following is an extract of the letter which accompanied the specimens. — 
'The inclosed is an insect which was very destructive to the American cotton which was 
sown here (Broach), on light alluvial soil. The ^^g is deposited in the germen at the 
time of flowering, and the larva feeds upon the cotton seed until the pod is about to 
burst, a little previous to which time it has opened a round hole in the side of the pod 
for air, and at which to make an exit at its own convenience, dropping on the ground, 
which it penetrates about an inch, and winds a thin web in which it remains during the 
aurelia state. Curious enough, the cotton on the black soil was not touched by it. 
The native cotton is sometimes affected by it'.'* 

** In the foregoing extract from Dr. Barn's letter it is interesting to remark, that 
the cotton grown from American seed is attacked in preference to any other, and that 
the cotton plant when grown upon ' black soil ' remains free from injury. The former 
fact may be accounted for by the American cotton being of a different species to that 
usually grown in India, and probably offers seeds which are more suitable to the 
development of the larva." Saunders^

specimens the costal area being almost destitute of dark shading. Exp. al. 18 — 21 mm. 
In the hindwings veins 3 and 4 are connate or stalked in both Indian and Hawaiian 
specimens. 

Although originally described from Indian specimens it is by no means certain that 
gossypiella is truly an Indian species for IJr. Barn's notes, as published by Saunders^ 
indicate strongly that the insect was imported with American Cotton which it preferred 
to the Indian species of Gossypium. Swinhoe and Cotes'^ record gossypiella from 
Cawnpore with a *'?" — this mark of doubt is misplaced, the specimen was correctly 
determined as gossypiella, Sndrs., the *' ?" had reference to its being wrongly described 
as a Depf'essaria by Saunders (Durrant and Meyrick have both referred gossypiella to 
Gelechia, Hb.). 

No special information accompanied this Cawnpore specimen (labelled *' Cotton, vi. 
1883"), but in the accumulation of ** Notes on insect pests from the Entomological 



MICROLEPIDOPTERA 733 

Section, Indian Museum," published by the late Lionel de Niceville in Indian 
Museum Notes, Vol. v. No. 3 (1903), we find (p. 183) under Eainas fabia that 
Egyptian Cotton was grown on the experimental farm at Cawnpore. It is 
therefore presumable that this specimen of gossypiella was associated with 
imported Egyptian Cotton. We also read (I.e. p. 183) that: *' On 4th December 
1893 the Director of Land Records and Agriculture, Punjab, Lahore, sent some 
pods [bolls] of Egyptian cotton, containing green and white insects tunnelling 
into the pods. A single moth was bred from these, but was unidentified." This 
bred specimen was regarded as probably a variety of Earias fabia, but it has been 
overlooked that Gelechia gossypiella was also bred from these Lahore Cotton bolls. 
Two specimens were sent to Merton (6010 — 11 Mus. Wlsm.) with the note "Cotton- 
boll moth reared from caterpillars from Lahore" (Cotes, i. 1., 19. 11. 1894) — these were 
determined as Gelechia gossypiella, Sndrs. (Drnt. Det. 1176 — 7: 1894). It would 
therefore seem that both the Lahore and Cawnpore specimens were imported with 
Egyptian cotton. We have no information as to the probable origin of the wSurat 
specimens recorded by Meyrick^ and may therefore assume that their history is similar 
to that of the other Indian specimens. Mr Perkins notes the Hawaiian specimens as 
*'Tineid of Cotton (introduced)" — unfortunately he gives no indication of the locality 
whence it came — and at present we have no evidence that the species occurs in 
America, but a single specimen from Japan (70795, Mus. Wlsm.) in very poor condition 
would seem to h^ gossypiella,

REMARKS. 

After long and careful study of the Microlepidoptera of Hawaiia it may be useful 
to make some general remarks upon such points as presented themselves during the 
progress of the work. Careful detailed analyses have been made to illustrate the 
geographical distribution of all the species and of some critical genera from which may 
be seen the proportions of those which may be regarded as autochthonous, or otherwise, 
as well as their interinsular relationship or representation. F'rom these it has been 
attempted at least to conjecture the probable origin of the Hawaiian P^auna. 

Until my own studies were approximately completed I had carefully avoided 
reading the prefaces to other papers already published upon different branches oS. the 
Entomology of these Islands, lest there should be any temptation to adopt conclusions 
arrived at by others rather than to form an independent opinion from the material in 
hand, but on comparing these prefaces with my own notes and analyses it is impossible 



738 FAUNA HAWAIIENSIS 

not to recognise that the observations made in any one paper are mainly applicable to 
all the others, and assuredly the Microlepidoptera suggest no exception to what appears 
to be the general impression as to the origin and present process of distribution of the 
species occurring in this group of islands. 

It may be observed that many years ago Frederick Smith and de Saussure (as 
quoted by Perkins) regarded the Aculeate Hymenoptera as of American origin, but 
Perkins dismisses this suggestion, from his own experience, as probably founded upon 
the study of what were mainly artificially-introduced species. 

In dealing with the Coleoptei^a Dr. Sharp mentions two genera of P legit hmy sides 
as seeming to be nearest allied to the genera Neoclyhis and Euryscelis which are found 
in North and Central America and in the Greater Antilles. We may be led to imply 
that he attributed an American origin to these genera, but I am unable to discover that 
he has indicated any leaning towards the adoption of a similar theory as concerning the 
majority of the Hawaiian Coleoptera, 

It is most remarkable that whereas the Gelechiadae are very largely represented in 
the western regions of North America these are nearly absent from Hawaiia, almost 
the only genera in this family being allied to Thyrocopa, Meyr., a group {Xyloryctidae) 
of distinctly Australian affinity. In fact the main indication of similarity throughout the 
Microlepidoptera, while pointing to a common origin, precludes the belief that such 
origin could have been either Asiatic or American. The survival of isolated remnants 
of an older fauna seems to be indicated, precisely such as might be expected to occur 
through the submersion of lower portions of some vast continent and the maintenance 
of its highest peaks in the form of oceanic islands. If the supposition of a lost 
'^paciftca" may not be acceptable, as accounting for the prevalent similarity which I have 
mentioned, some other theory must be devised, possibly even less capable of support by 
the evidence of facts and at least equally beyond the possibility of precise proof. 

One thing certainly strikes us very forcibly in regard to the close affinity of species 
and the extreme difficulty of finding reliable and persistent generic characters, viz. that 
the Hawaiian Microlepidoptera are in a condition of progressive, and at present imperfect, 
differentiation. For, whereas in all other continental collections we find an abundance 
of distinct and easily recognisable species and genera, intermixed with some few only 
difficult to identify, the Hawaiian Microlepidoptera are in the great majority of instances 
so closely allied, or so confusingly similar, as to present the utmost difficulty in any attempt 
at classification or description. Each prevalent form seems to possess representatives 
in the various islands, but these are scarcely ever absolutely inseparable in series, and 
possess in each case some distinctive peculiarity of colour, or markings, or secondary 
sexual characters, which seems to entitle them to recognition as at least geographical 
species. It is not uncommon to find in a long series of specimens, apparently similar 
at first sight, that a certain proportion of the males possess an expansible subcostal 
hair-pencil at the base of the hindwings which is^ wanting in others, and a minute 



MICROLEPIDOPTERA 739 

examination usually discloses persistent differences, however slight, which enable the 
species to be distinguished from each other in either sex. I was at first disposed to 
regard this sexual character as of generic value, but the idea was ultimately abandoned 
in view of the varying degree in which it was represented, and of the precise similarity, 
in all other structural details, of the very numerous specimens under observation. The 
same plasticity extends to other structural characters, such as the pecten on the basal 
joint of the antennae, the clothing of the tibiae, the comparative breadth of the fore and 
hindwings, and the relative length of the palpal joints ; the neuration also is occasionally 
unstable (see remarks under the genus Diplosara, Meyn, pp. 646 — 7, etc.). 

The absence of Oecophoridae, one species, Ethmia colonella (introduced), repre- 
senting this family, is the most notable point in which the Hawaiian Tineina differ from 
those of Australia, for Oecophoridae are probably more abundantly represented there 
than any other family. 

Microlepidoptera ought to prove very useful in determining the affinities of the 
Hawaiian fauna. Their extremely delicate nature, short lives, and restricted food- 
plants cause the majority of them to be very locally distributed, and thus less likely to 
be imported than other more enduring forms — some few exceptional instances are 
referred to. 

The Microlepidopterous Fauna of Hawaiia is almost exclusively autochthonous, 
having apparently been formed through the splitting-up of species by compulsory 
segregation. This would naturally occur under the hypothesis that these islands 
represent merely the tops of mountain ranges formerly belonging to one continent over 
which, before such isolation, these species had a wide range with no special cause for 
variation. The study of ethnology, and of the languages, habits, and superstitions of 
native races seems to support the theory of a common origin, and, given a Pacifican 
Fauna we should expect it to persist in isolated groups of islands extending from Hawaiia 
to New Zealand, and, so far as one can judge, this appears to be the case. 

The following extracts are from Ellis' Polynesian Researches, iv. (2nd edn. 1831.) 
Discussing the question of the Pacific Islanders having "an Asiatic, and probably a Malayan, origin." — 

"The natives of the eastern part of New Holland, and the intertropical islands within thirty degrees east, 
including New Caledonia, the New Hebrides, and the Figiis, appear to be one nation, and in all probabiHty 
came originally from the Asiatic islands to the northward, as their skin is black, and their hair woolly or 
crisped, like the inhabitants of the mountainous parts of several of the Asiatic islands. But the inhal)itants of 
all the islands to the east of the Figiis, including the Friendly Islands and New Zealand, though they have 
many characteristics in common with these, have a number essentially distinct. 

The natives of Chatham Island and New Zealand, in the south ; the Sandwich Islands, in the north ; 
the Friendly Islands, in the west; and all the intermediate islands, as far as Easter Island, in the east, are one 
people. Their mythology, traditions, manners and customs, language, and physical appearance, in iheir main 
features, are, so far as we have had an opportunity of becoming acquainted with tliem, identically the same, 
yet differing in many respects from those of the islands to the westward of Tongatabu. 

The dress of the Figiians, &c. is not the same as that of the natives of New Zealand, Tahiti, and the 



740 FAUNA HAWAIIENSIS 

other islands; they do not appear to wear the cloak, or the tiputa. In war, they throw long spears to a 
considerable distance, and use the bow and arrow, which the others only employ in their amusements. 

The difference in their physical character is greater ; the dark complexion, woolly hair, and slender make, 
indicate them to be a different people. 

Various points of resemblance have been shewn between the aborigines of America and the natives of 
the eastern islands of the Pacific, in their modes of war, instruments, gymnastic games, rafts or canoes, treat- 
ment of their children, dressing their hair, feather head-dresses of the chiefs, girdles, and particularly the tiputa 
of the latter, which in shape and use, exactly resembles \\\^ pojicho of the Peruvians. 

These circumstances seem to favour the conjecture, that the inhabitants of the islands west of Tongatabu 
have an Asiatic origin entirely ; but that the natives of the eastern islands may be a mixed race, who have 
emigrated from the American continent, and from the Asiatic islands ; that the proximity of the Friendly and 
Figii islands may have given both a variety of words and usages in common, while the people to which the 
former belong have remained in many respects distinct. 

The nation inhabiting the eastern part of the Pacific has spread itself over an immense tract of ocean^ 
extending upwards of seventy degrees north and south from New Zealand and Chatham Island to the Sandwich 
group, and between sixty and seventy degrees east and west from Tongatabu to Easter Island. This last is 
not farther from the islands adjacent to the continent than some of these groups are from any other inhabited 
island. The Sandwich Islands are above twenty degrees from the Marquesas, and thirty-six from Tahiti, yet 
inhabited by the same race of people." (Elhs, 1. c. 432 — 4.) 

The people of Haivaii. 

"They said they were informed by their fathers, that all the land had once been overflowed by the sea, 
except a small peak on the top of Mouna-Kea, where two human beings were preserved from the destruction 
that overtook the rest, but they said they had never before heard of a ship, or of Noah, having always been 
accustomed to call it the kai a Kahindrii (sea of Kahinarii)." (Ellis, 1. c. 441—2.) 

"The general opinions entertained by the natives themselves, relative to their origin, are, either that the 
first inhabitants were created on the islands, descended from the gods by whom they were first inhabited, or 
that they came from a country which they called Tahiti." (Ellis, 1. c. 428.) 

"In former times, when there was nothing but sea, an immense bird settled on the water, and laid an 
egg, which soon bursting, produced the island of Hawaii. Shortly after this, a man and woman, with a hog, 
a dog, and a pair of fowls, arrived in a canoe from the Society Islands, took up their abode on the eastern 
shores, and were the progenitors of the present inhabitants." (Ellis, 1. c. 430.) 

"Another account prevalent among the natives of Oahu, states, that a number of persons arrived in a 
canoe from Tahiti." (Elhs, 1. c. 430.) 

" Tahiti is the name of the principal island in the group, called by Captain Cook the Georgian Islands. 
It is the Otaheite of Cook ; the Tditi of Bougainville ; and the Taheltee^ or Tahitee^ of Forster. In the 
language of the Georgian and Society Islands, the word taJiiti also signifies to pull up or take out of the 
ground, as herbs or trees are taken up with a view to transplantation, and to select or extract passages from a 
book or language, to be translated into another. Hence a book of scripture extracts is called, words, tahitihea''' 
(Ellis, 1. c. 431.) 

Tahiti "seems equivalent to the English word abroad, as applied to parts beyond the sea." (Ellis, I. c. 

431-) 

Society Islands. 

"Raiatea is not only the most important island of the Leeward group, from its central situation and its 
geographical extent, but on account of its identity, in tradition, with the origin of the people, and their pre- 
servation in the general deluge. It has been distinguished as the cradle of their mythology, the birth-place 
and residence of Oro, the region to which disembodied spirits resorted, the seat of their oracle, and the abode 
of those priests whose predictions for many generations regulated the expectations of the nation. It is also 
intimately connected with the most important matters in the traditional history and ancient religion of the 
people." (Ellis, 1, c. 11. 314 — 5.) 



MICROLEPIDOPTERA 



741 



"In some of the ancient traditions of the Society Islands, Opoa, in Raiatea, the most celebrated place in 
the islands, the birth-place of Oro, and the spot where the human species were created, &c. is called HawaiiP 
(Ellis, 1. c. IV. 431.) 

*'Opoa is the most remarkable place in Raiatea; of its earth, according to some of the traditions, the first 
pair were made by Tii, or Taaroa, and on its soil they fixed their abode. Here Oro held his court. It was 
called Hawaii ; and as distant colonies are said to have proceeded from it, it was probably the place at which 
some of the inhabitants of the South Sea Islands arrived. It has also long been a place of celebrity, not only 
in Raiatea, but throughout the whole of the Society Islands. It was the hereditary land of the reigning family, 
and the usual residence of the king and his household.^' (Ellis, 1. c. 11. 314 — 5.) 

Language and Cust07ns. 
The same method of salutation (rubbing noses) practised by all the inhabitants of the Pacific, also 
in Madagascar, this custom is called '' Ho-gnV (New Zealand); "- HoV (Tahiti); '' HonV (Hawaiia). 
(Ellis, 1. c. 337.) 

Mr. Perkins informs me that a very large proportion of the species dealt with in 
this paper were obtained by searching upon trunks of trees and among dead leaves 
under forest growth. As might be expected under such circumstances many of them 
were proved to be case-bearers, and without doubt this habit is characteristic, especially 
of such genera as are found rich in species. The most commonly known European 
case-bearing Tineina are those of the genus Coleophora, Hb., and it is at least a 
coincidence that in the perfect state these are also extremely difficult to distinguish from 
each other without some knowledge of their preliminary stages. Many attempts have 
been made to recognise characters of generic value among the numerous species of this 
genus, but Coleophora, as now generally accepted, presents a gradation of structure 
which not only fails to afford satisfactory lines for higher classification, but sometimes 
increases the difficulty of determining the limits of rightly accepted species. This 
applies specially to the more or less fugitive hair-scales at the base of the antennae, 
sometimes well-developed, sometimes weak, and often absent. If all the known species 
of Holarctic Coleophorae (many of them represented by a single specimen) were mixed 
together in a series of store-boxes it would not be more difficult to identify the species 
correctly, without any clue to their life-histories, than it has been to work through a 
correspondingly numerous collection of the genus Hyposmocoma, BtL, consisting of at 
least I 70 species, and to determine the limits of special variation. Yet it will be obvious 
to anyone acquainted with the subject that a series of Coleophorae selected at random 
would almost certainly include several consistently distinct species. 

If the above illustration may convey some idea of the interminable series of 
mutations by which the differentiation of species has progressed, a study of generic 
characters is almost equally confusing. The general notion derived from such study is 
that the process of branching from a common stem must have commenced before the 
evolution of some of our best-known and hitherto easily recognised families — e.g. 
Meyrick's diagnostic separation of the Elachistidae from the Hyponomeuiidae ( =P Intel- 
lidae, Meyr.) on the comparative breadth of the hindwings can no longer be maintained. 
The variation in these forms in Hawaiia is evidently greater than any that occurs 
F. H. I. 95 



742 FAUNA HAWAIIENSIS 

among their congeners in Australia, although the Australian Fauna, from which 
Mey rick's experience has been largely derived, is supposed to be one of the oldest — 
the question arises, are we not dealing with a fauna derived from forms ancestral even 
to those which have been preserved in that region ? 

It would be easy to select many instances of what might be called either broad- 
winged Elachistidae, or narrow-winged Hyponometdidae (connected by intermediate 
forms) from among the material with which I have dealt, and the conclusion is forced 
upon us that such radiation from a common stock as may be presumed to have occurred, 
dates from a period antecedent to the differentiation of these hitherto accepted families, 
and although elsewhere their connecting links seem to have disappeared, yet, so far as 
this limited fauna is concerned, they cannot be separated, and can therefore no longer 
be regarded as separable. 

It may be interesting to observe the proportionate number of species represented 
in the Hawaiian Islands, according to our present acquaintance with what are known 
as the Macrolepidopiera and the Microlepidoptera, 

Meyrick's list contains 292 species (including the Rhopalocerd) and he has worked 
out all the families to the end of the Pyralidina. 

Of the Pterophorina and Tineina, which are now dealt with, I have distinguished 
441 species, and although it is possible that some few of these forms may eventually 
be found to be varietal, rather than special, the actual proportions will almost certainly 
be readjusted by the future differentiation of others which are here regarded as varieties. 

Thus the numerical relation borne by the micros to the macros is 441 to 292, while 
the endemic proportion is 420 to 261, 

Mr. Perkins devoted a great deal of time to the Maci^olepidoptera, and it was only 
when he failed to find species not previously met with that he gave special attention 
to the smaller forms. It is therefore reasonable to regard the above proportions as 
approximately representing the facts of the case. I have every reason to believe that 
if an equally extensive knowledge of the fauna of other portions of the world's surface 
could be acquired it would be found in the majority of cases that somewhat similar 
proportions would be maintained, and we look back with some surprise to Stainton's 
delight and astonishment when he first received Indian Microlepidoptera from Atkinson, 
so late as the year 1855, and still more to the statement of Curtis, at the same date 
(Pr. Ent Soc. Lond. 1855, 93 — 4), that he doubted whether Microlepidoptera would be 
found so plentiful in tropical countries as Stainton anticipated on the strength of this 
consignment because during a late expedition in the South of Europe in company with 
Francis Walker, during which they sought especially for Microlepidoptei^a, the number 
of small moths among their 6000 captures was very few. Perhaps Walker shared 
Curtis' views before he became a too-prolific author of descriptions of exotic micros ! 

Before Mr. Perkins so laboriously and persistently dragged these Hawaiian Tineina 
from their obscurity 35 species only, as now admitted, had been described ; i by 



MICROLEPIDOPTERA 743 



Durns 



Walker, 29 by Butler, and 5 by Meyrick, the two latter authors working out Blackbi 
collections. Mr. Meyrick also collected a few species in Oahu himself, in 1883, which 
by his courtesy are included in the present paper. I have also to thank him especially for 
having lent me all his material, including types of his own species and genera, and such 
exponents of Butler's species as Blackburn had numbered and retained for his own use. 

It will be recognised by all practical workers that the examination of so large a 
collection has been no easy task. The specimens, although for the most part in good 
condition, were merely pinned on blocks of cork with a dated locality label beneath. 
On each block were insects of various sizes, thus every specimen had to be provisionally 
registered before they could be relaxed in groups selected according to size, and 
therefore according to the amount of moisture required, the provisional labels being of 
course rendered useless after damping, and serving only to preserve a reference to the 
details in MS. All were repinned and set. The amount of mere manual labour which 
this involved has been a severe tax upon the time and industry of my assistant 
Mr. Durrant, but that was after all only the lighter part of his work. He has also 
undertaken for me a detailed examination of structural characters, and the sorting-out 
of species and genera preparatory to final arrangement and description. 

If anything could have damped the enthusiasm of a specialist devoted to his 
subject the genera Hyposmoco7na, Aphthonettis, Neelysia, and Heterocrossa would 
assuredly have done so, but in verifying his work I have found scarcely any errors and 
these only such as were absolutely unavoidable in dealing with such a mass of 
material. He examined the neuration and other minute structural characters of eve^y 
specimen in the collection. Many which were almost absolutely similar in colour and 
markings were found to differ in more important respects, and the discovery oi one 
difference invariably led to the recognition of others which had at first sight been over- 
looked. Generic separation, which at first seemed obvious, had frequently to be 
discarded as valueless, and the work had thus to be done three or four times over 
before a satisfactory conclusion could be reached. I cannot sufficiently commend, or 
acknowledge, the patience and perseverance with which he has relieved me of by far 
the greater part of this labour and made my task, if not actually easy, yet far less 
painfully exhausting than his own. 

Whatever remarks are to be found in prefaces to other papers on Hawaiian 
entomology are in entire sympathy with the above-mentioned experiences as to 
variability and plasticity, and the consequent difficulties of precise differentiation and 
classification. 

The analytical tables w^ill be found to supply the evidence, which has led to the 
conclusions adopted above, and in nearly all cases a remarkable symmetry will be 
observed between these and similar tables which accompany the work of other entomo- 
logists — most noticeably perhaps with regard to the ratio of endemic and apodemic 
species, and to the proportionate numbers of each as represented in particular islands.

FAMILY TYPE. 

The impression produced is that generahsed (archaic) forms are absent from 
Hawaiia: the fauna is a specialised one, but derived from now extinct palaeomorphs. 
Evolution in Hawaiia has taken place in a manner locally peculiar, and correlation with 
other faunae seems impossible, owdng to the extinction of those forms from which the 
faunae of Australia and New Zealand were likewise derived on diverging lines, the 
points of divergence having been eliminated. 

GENERA. 

26 Genera are endemic, of which Hyposmocoma, Btl., contains no less than 177 
species ; 36 are apodemic (Total 62). Of the apodemic genera five only present points 
for consideration, the others being widely distributed, and of no local interest.

Oecia may be dismissed as a domestic species, introduced by commerce, probably 
via San Francisco. 

Lineodes [Pyralidina, not properly a micro, vide p. 469), has not yet been recog- 
nised in Australia or the Pacific and is the only really American element in the entire 
fauna — it can at most be regarded as a mere straggler. 

Ereunetis, Stoebci^kinus, and AiUosticha are Pacifican morphs, the first extending 
to the West Indies, and perhaps occurring in Colombia. 

The endemic genera are of Pacifican origin, and comparison would be made with 
Australian, or New Zealand, geneomorphs; Eccoptocera is allied to the North American 
Proteopteryx, Wlsm., but it is equally allied to the Australian genera Strepsicrates, 
Meyr. (which has been recorded from the West Indies, and occurs also in the United 
States and the Canaries), Bathroioma, Meyn, etc. 



SPECIES. 

The following is a careful analysis of the 441 species as now recorded from 
Hawaiia: of these 420 are endemic and 21 apodemic. 336 endemic and 8 apodemic 



756 



FAUNA HAWAIIENSIS 



{ = 344) species are confined to single Islands, while 85 endemic, and 12 apodemic ( = 97) 
species occur in more than one Island. Five species Hyposmocoma htpella, Wlsm., 
Prays fulvocanellus, Wlsm., Eccoptoce^^a foetorivorans, Btl, Crocidosema plebeiana, Z., 
and Bactra straminea, Btl. occur in each island, of these Crocidosema plebeiana is 
apodemic.

Crocidosema plebeiana, Z., Trichoptilus oxydactyhis, Wkr., and Setomorpha rtdella, 
Z., are widely distributed, and probably not artificially introduced. 

Plutella maculipennis, Crt., is universally distributed, feeding on cabbages and 
other Cruciferae. It is difficult to determine the natural range of this species which 
F. H. I. 97 



75^ FAUNA HAWAIIENSIS 

has undoubtedly been extended by commerce — only if the larva feeds on no native 
Crucifer in Hawaiia would it be possible to demonstrate that the insect has been intro- 
duced, although probably this is the case. 

Bedellia somnulentella, Z., and minor, Busck— These species feed on Convolvulus 
and Ipomoea ; the former is widely distributed, the latter, which has been recently 
differentiated, was hitherto only known to occur in Texas. Two endemic species of 
Bedellia are found in Hawaiia, and others in Australia, it is therefore possible that these 
two have not been artificially introduced, 

Phthoriniaea operctilella, Z., mines the leaves of Tobacco, and bores into the 
tubers of the Potato, causing serious damage. It is now widely distributed, and carefully 
weighing the evidence deducible from the long list of references given under this 
species (pp. 483 — 4), it would appear to have originated in the United States, where 
it feeds also on other Solanaceae, and was doubtless introduced to the Islands via San 
Francisco. 

Gelechia gossypiella, Sndrs., is noted by Mr. Perkins as an introduced species, 
highly injurious to Cotton, at Honolulu ; it is recorded from India and Japan, but is not 
known to occur in America. 

Tinea fuscipunc tell a, Hw., Monopis crocicapitella, Clms., Monopis monachella, Hb., 
Endrosis lactella, Schifif, and Oecia niactdata, Wlsm., are domesticated species, doubtless 
introduced by commerce, Oecia maculata, hitherto only recorded from Brazil and the 
West Indies, is common in houses, having the same habits as Endrosis lactella — it 
probably ranges through Central America (a second species occurring in Costa Rica), 
and was not improbably introduced to the Islands from San Francisco, where it will 
doubtless be found. The American Monopsis crocicapitella, Clms., is now recognised 
as identical with a European species disguised under the synonyms hyalinella, Stgr., 
lonibardica, Hrng., and heringi, Rdsn. ; this also occurs in Tenerife. 

Archips postvittamis, Wkr., is certainly an importation from Australia, where it is 
common and very variable ; Mr. Perkins also notes its occurrence in New Caledonia. 
The late Francis Walker established a record when dealing with specimens of this 
species, describing them under 1 2 different idionyms distributed among 4 genera in two 
subfamilies of the Tortricidae, 

Ereunetis minuscula, Wlsm., is from the West Indies (and probably Colombia), 
while E, simulans, Btl., occurs in the Marquesas and Fiji — other species are found in 
Australia, and allied genera in Malaysia and Africa, it would therefore appear that these 
forms are widely distributed, and it would be rash to assume that they have been 
introduced. 

Platyptilia fuscicornisy Z., only hitherto recorded from Colombia, is probably more 
widely distributed, but confused with cosmodactyla, Hb., and acanthodactyla, Hb., this 
may, or may not have been introduced — evidence is wanting. 

Stoeberhinus testacetis, Btl., Opogona aurisquamosa, Btl., and Ej^eunetis simulans^ 



MICROLEPIDOPTERA 759 

Btl., are Pacifican forms, all occurring in the Marquesas, atirisquamosa in the Society 
Islands, and simulans in Fiji. 

The distribution of the remaining two species is peculiar, Stag7natopho7'a Jionorariella, 
Wlsm., occurring in Pitcairn Island, while its close ally Stagmatophora qiiad^H fas data, 
Wlsm., is found in New Guinea. 

Ethmia colonellay Wlsm., although not yet recorded elsewhere, has almost certainly 
been imported from Malaysia, but so much error has been introduced under the name 
''hilarella, Wkr.," which was the original record of this species from Hawaiia, that great 
caution is needed in tracing its derivation. Let it be noted that there are several 
yellow hind-winged forms of Ethmia allied to colonellay very closely related to each 
other, but distinct, and that ^bicolorella, Pgnstk. (nee Gn.), from Malaysia, appears to 
be identical with colonella.
